Why teams migrate from Hapily to Events OS
Hapily is a good product — ARISE GTM rated it 8.5/10 in our Best HubSpot Event Software 2026 comparison. For many mid-market teams, it solved the right problem in 2022: getting B2B event data out of external platforms like Eventbrite and into HubSpot's native custom object model.
TL;DR: Hapily-to-Events-OS is the simplest migration in the event platform category because both products already store data in HubSpot custom objects — you're not re-platforming data, you're moving configuration and upgrading what the data does.
Install Events OS via OAuth in three minutes, map your Hapily schema to Events OS objects, migrate workflows, run one event in parallel, cut over.
Typical timeline: 1–2 weeks. What you gain: automatic four-layer pipeline attribution (Hapily needs manual configuration), AI event setup in under two minutes (Hapily has none), cross-event benchmarks that compound (Hapily is static).
What you lose: recurring Hapily subscription (typically $7,499–$14,999/year), the requirement to run HubSpot Enterprise, and Hapily's packaged CMS theme for event landing pages — Events OS does not currently ship a page builder, so teams bring their own HubSpot CMS pages or use third-party registration pages.
Migration typically happens for three reasons — the same three things ARISE Events OS does that Hapily doesn't:
1. The money. Hapily manages events. Events OS proves pipeline. Hapily gives you the building blocks to track attribution but you build the workflows yourself. Events OS runs four-layer attribution (Registration → Contact → Company → Deal) automatically on every event completion. Teams that have been manually configuring Hapily attribution for 12–18 months eventually ask why they're doing it by hand.
2. It doesn't learn. Hapily is static. Events OS is AI-native — AI event setup in under two minutes, no-show risk scoring, invite recommendations from CRM scans, meeting agent that suggests follow-ups, post-event narrative generation. Teams running 20+ events a year reach a point where manual setup and follow-up are the bottleneck, not the platform.
3. It doesn't benchmark. Hapily reports per-event. Events OS benchmarks across the portfolio — cross-event intelligence on Growth tier, full Event Series intelligence on Scale. By event thirty, Events OS is running a smarter programme than you could design from scratch. Hapily still treats every event as its first.

When migration makes sense
Migrate from Hapily to Events OS when:
- Attribution reporting in Hapily is taking manual effort and still not giving the CFO what they want
- Event volume is scaling past 20 events a year and manual setup is the bottleneck
- HubSpot Enterprise tier is expensive and you only need it for Hapily — Events OS runs on Professional
- Pricing is becoming uncomfortable — Hapily's $7,499–$14,999/year vs Events OS's £3,495–£11,995/year
- AI-driven features (setup, scoring, invites, meetings) would free up real team time
Don't migrate when:
- You're running fewer than 5 events a year and Hapily's packaged experience is fine
- You've heavily customised Hapily with CMS modules that would take significant rebuild
- Your team specifically prefers Hapily's management UI over HubSpot-native views
The key advantage: your data is already native
The migration detail most people miss. Hapily deploys custom objects into HubSpot — Event, Session, Attendee, Registrant, Ticket, Speaker are actual HubSpot custom object records visible in your CRM, usable in workflows and lists.
This means:
- No data migration in the traditional sense. Records are already in HubSpot.
- No sync cutover risk. Data isn't moving.
- Migration is about configuration, not data movement.
The work is mapping Hapily's schema to Events OS's schema, migrating any custom workflows you built on top of Hapily objects, and decommissioning Hapily's app-layer UI.
This is why Hapily-to-Events-OS is the shortest migration in the event platform category — typically 1–2 weeks vs 4–6 weeks for an Eventbrite or Goldcast migration.
The 6-phase migration playbook
Phase 1 — Install Events OS and audit Hapily config (Day 1–2)
Install Events OS.
- Go to Events OS install and OAuth connect to your HubSpot portal. Takes three minutes.
- Events OS deploys its custom object schema into your HubSpot instance (non-destructive — doesn't touch Hapily's objects).
- You're now live on the Starter tier's 14-day free trial. No credit card required.
Audit Hapily configuration in parallel:
- Registration page templates and customisations
- Event type variations (webinar, workshop, conference, hybrid)
- Custom properties added to Hapily's standard objects
- Hapily workflow actions (registration, attribution, follow-up)
- CMS theme modules in use
- Attendance tracking configuration (QR, manual, virtual)
- Reporting dashboards built on Hapily objects
Deliverable: Events OS live in your portal (trial mode). Configuration inventory of Hapily ready to map.
Phase 2 — Map schemas (Day 2–3)
Because both products use HubSpot custom objects, schema mapping is straightforward. Standard mapping:
| Hapily object | Events OS object | Notes |
|---|---|---|
| Event | Event | Direct mapping |
| Session | Session | Direct mapping |
| Registrant | Registration | Same concept, different name |
| Attendee | Attendance (on Registration) | Events OS treats attendance as a property, not a separate object |
| Ticket | (Optional) Registration type | Only needed if using paid ticketing |
| Speaker | Speaker | Direct mapping |
Custom properties you added to Hapily objects map directly onto Events OS objects. Since they're all native HubSpot custom properties, no translation is needed — it's a property-to-property mapping.
Deliverable: Schema mapping document.
Phase 3 — Migrate configuration (Day 3–7)
This is the bulk of the work.
Registration pages — plan this early. This is where the trade-off is biggest. Hapily ships a packaged CMS theme that renders your event pages; Events OS does not. During migration, decide on one of three approaches:
- Option A: Keep Hapily pages running until cutover. Hapily continues rendering event pages, and Events OS handles everything else. At final cutover, pages need to move to one of the options below.
- Option B: Use HubSpot CMS pages you build or already have. Most teams already have a branded HubSpot CMS with templates. Build event landing pages there and drop a native HubSpot form that writes to Events OS's custom objects.
- Option C: Use a third-party registration page tool (Typeform, Gravity Forms, etc.) that posts to HubSpot. Events OS captures the data the same way.
For existing active Hapily events, let them run out on Hapily's pages — don't migrate pages mid-event.
Workflows. Map every Hapily workflow action to an Events OS equivalent. The big shift here is attribution — Hapily's manual attribution workflows can typically be deleted entirely, because Events OS runs four-layer attribution automatically. Teams usually discover 3–5 Hapily workflows that become redundant. For event setup (registration confirmation, reminders, post-event flows), Events OS's AI event setup generates the HubSpot workflows in under two minutes per event type.
Attendance tracking. Events OS includes mobile-web QR check-in at all tiers. If Hapily's QR scanner was configured, you'll reconfigure the flow in Events OS — straightforward because both write to HubSpot custom objects.
Reporting. Any custom reports built on Hapily custom object properties need property mapping updates to point at Events OS objects. Most teams also take this chance to replace Hapily's per-event reporting with Events OS's portfolio dashboard — and if on Growth tier, the cross-event benchmarks.
Management UI. Your team moves from Hapily's separate app UI to Events OS's agentic card inside HubSpot's CRM. Plan 1–2 hours of team familiarisation — no formal training required because the card lives on the HubSpot records your team already uses.
Deliverable: Fully configured Events OS running alongside Hapily, registration page plan decided, ready for parallel test.
Phase 4 — Historical data (Day 7–10)
Two paths:
Path A: Keep Hapily records in place. Leave historical Hapily custom object records as they are. Going forward, new events use Events OS's schema. You keep historical reporting via Hapily object queries, and new reporting on Events OS. This is the fast path — no data migration required.
Path B: Consolidate under Events OS schema. If you want one unified schema going forward, migrate Hapily records into Events OS objects. Export from Hapily via CSV or HubSpot API, transform properties to match Events OS schema, import using HubSpot import tools. Preserve original timestamps.
Most teams take Path A for the first 3–6 months, then migrate historical data later if unified reporting becomes a priority. There's no urgency — Hapily records don't degrade.
Deliverable: Historical data path decided, migration executed or deferred.
Phase 5 — Parallel run (Day 10–12)
Run one event through Events OS while Hapily continues to operate. Validate:
- Events OS registration page captures all data correctly
- Confirmation emails render correctly with your branding
- Workflows fire (registration → native HubSpot workflow triggers → confirmation + calendar invite + sales alert)
- Attendance tracking works at check-in
- Four-layer attribution flows to associated deals automatically
- Portfolio dashboard reflects the event
If on Growth or Scale, also validate:
- No-show risk scoring surfaces before the event
- Deal Room populates with attendee-deal matches
- Cross-event benchmarks update
Fix anything that doesn't work before cutover.
Deliverable: Parallel-run sign-off.
Phase 6 — Cutover and uninstall Hapily (Day 12–14)
- Publish new event registration pages on whichever page option you picked in Phase 3 (HubSpot CMS or third-party tool) for all upcoming events
- Update marketing channels — email templates, website CTAs, social campaigns — to point at new registration URLs
- Run out any active Hapily events through their natural end date
- Convert Events OS trial to paid (if not already) at the tier that matches your volume and feature needs
- Cancel Hapily subscription at next renewal date (check contract — may need notice)
- Uninstall Hapily app from your HubSpot portal once the last Hapily event concludes
Important: uninstalling Hapily removes its CMS modules. Before uninstalling, verify every public event page is now rendered outside Hapily — either on your own HubSpot CMS pages or via a third-party tool. Events OS does not currently provide CMS modules to replace Hapily's.
Deliverable: Live Events OS, Hapily uninstalled, Hapily subscription cancellation queued for renewal.
Cost comparison over three years
Modelled for a team running 50 events per year on Hapily. Exact Hapily cost depends on registration credit volume consumed — 50 events × 200 attendees = 10,000 annual registrations, well beyond Hapily's 2,000-credit entry tier, so pricing sits in the middle-to-upper end of the $7,499–$14,999 range.
| Cost component | Hapily (stay) | ARISE Events OS (migrate) |
|---|---|---|
| Year 1 subscription | $7,499–$14,999 (~£5,900–£11,800) | £6,995/year (Growth tier) |
| Year 2 subscription | £5,900–£11,800+ (credits may require tier step-up) | £6,995/year |
| Year 3 subscription | £5,900–£11,800+ | £6,995/year |
| HubSpot tier required | Enterprise | Professional+ |
| Registration fees | Credit-based (1 per registrant) | Unlimited |
| HubSpot stack cost implication | Requires Enterprise | Works on Professional (potential saving) |
| 3-year subscription | ~£17,700–£35,400+ | £20,985 |
Direct subscription savings vary by where your current Hapily contract sits in the credit-pricing range. Teams at Hapily's upper tier (running high event volume) save meaningfully; teams still on entry tier pay roughly the same. The bigger potential saving is downgrading HubSpot Enterprise to Professional if Events OS is the only reason you're on Enterprise — this can save £500–£1,000+ per month depending on seats.
What you also get: AI event setup (2 min builds vs manual), automatic four-layer pipeline attribution (vs manual workflow configuration), cross-event benchmarks (vs static per-event reporting). Pricing is only half the case for migration — the capability gap is the other half.
Common migration pitfalls
Pitfall 1: Trying to migrate during a heavy event week
Don't. Pick the lowest-volume fortnight you have. With only 1–2 weeks of migration effort, there's almost always a quiet window you can target.
Pitfall 2: Cancelling Hapily before Events OS is validated
Don't cancel the subscription until at least one full event has run cleanly on Events OS. Parallel-run in Phase 5 is non-negotiable.
Pitfall 3: Uninstalling Hapily before page strategy is implemented
Uninstalling Hapily removes its CMS modules and packaged theme. Events OS does not currently ship replacement CMS modules or a page builder. Before you uninstall Hapily, verify every public event page has been rebuilt on your HubSpot CMS or moved to a third-party registration tool — otherwise your public event pages will break.
Pitfall 4: Rebuilding attribution workflows that Events OS handles automatically
A common waste of time in migrations. Before rebuilding any Hapily attribution workflow in Events OS, check whether Events OS's four-layer attribution already handles it. It usually does.
Pitfall 5: Missing Hapily contract notice requirements
Hapily contracts often auto-renew with 30–60 day notice windows. Start the cancellation process in Phase 1, not Phase 6. You don't want to finish migration only to discover you're stuck paying for another year.
Migration timeline
| Phase | Duration | Critical path |
|---|---|---|
| 1 — Install Events OS + audit Hapily | 1–2 days | OAuth install + config inventory |
| 2 — Schema mapping | 1 day | Object-to-object mapping |
| 3 — Migrate configuration | 3–5 days | Workflows + CMS + reports |
| 4 — Historical data decision | 1–3 days | Path A (defer) vs Path B (migrate now) |
| 5 — Parallel run | 2–3 days | At least one full event |
| 6 — Cutover + uninstall | 1–2 days | Marketing channel updates + app uninstall |
| Total | 1–2 weeks | — |
The bottom line
Hapily-to-Events-OS is the simplest migration in the event platform category because your data is already in HubSpot. The work is replacing Hapily's static management layer with Events OS's AI-native intelligence layer — automatic attribution, AI event setup, cross-event benchmarks.
Typical outcome: direct subscription saving, potential HubSpot tier downgrade (Enterprise → Professional), meaningful operational time saving from AI-driven setup and follow-up, and event infrastructure that gets smarter instead of staying static.
The three-year maths favours Events OS at any volume above 10 events a year when you factor in AI time savings and attribution improvement. Below that threshold, Hapily's packaged experience may still be worth the premium — but honestly, at that volume Events OS Starter (£3,495/year) undercuts Hapily's entry tier too.
If you're reviewing a Hapily renewal, this is the playbook.
Frequently asked questions
Why migrate from Hapily to ARISE Events OS?
Three reasons: (1) Events OS does automatic four-layer pipeline attribution — Hapily requires manual configuration; (2) Events OS is AI-native (event setup in 2 minutes, no-show scoring, invite recommendations, post-event narratives) — Hapily has none of this; (3) Events OS benchmarks across events — Hapily reports per-event only. Plus pricing: Events OS is cheaper at every tier and runs on HubSpot Professional, not just Enterprise.
How long does Hapily-to-Events-OS migration take?
Typically 1–2 weeks. This is the shortest migration in the event platform category because Hapily's data is already in HubSpot custom objects — migration is about moving configuration and workflows, not migrating data. Install Events OS via OAuth in 3 minutes, then 1–2 weeks to map schema, rebuild configuration, parallel-run, and cut over.
Will I lose event data during migration?
No. Hapily stores event data in HubSpot custom objects that are already in your portal. Two options: (a) leave historical Hapily records in place and use Events OS for new events — no migration required; (b) consolidate everything under Events OS schema via property mapping and import — takes 1–2 days extra.
How much does Hapily-to-Events-OS migration cost?
Events OS starts at £3,495/year (Starter), £6,995/year (Growth), or £11,995/year (Scale) with unlimited registrations. There's no one-time migration cost beyond your team's time (typically 20–40 hours across the 1–2 week window). Compared to Hapily's credit-based $7,499–$14,999/year pricing, teams running higher event volumes typically save meaningfully on subscription; teams at Hapily's entry tier pay similar amounts but gain unlimited registrations and the AI capability set Hapily doesn't offer. Migration payback: 3–6 months.
Can I keep using Hapily during migration?
Yes. Hapily continues running your event programme through Phases 1–5. Only at Phase 6 cutover do new events move to Events OS. Existing Hapily events run to their natural end date.
What happens to Hapily's custom objects when I uninstall?
Hapily's custom object definitions typically remain in your HubSpot portal after uninstall, but Hapily-specific CMS modules, the packaged theme, and management UI disappear. Plan your page strategy (HubSpot CMS you own, or third-party registration tool) before uninstalling — Events OS doesn't currently include a CMS page builder or theme to replace Hapily's.
Do I need a HubSpot Partner to migrate?
Not required. Events OS is designed for self-service migration — OAuth install, AI event setup handles most configuration. That said, ARISE GTM (HubSpot Platinum Solutions Partner and creators of Events OS) can provide migration support for teams with complex Hapily configurations or limited internal HubSpot capability.
Will my attribution improve after migration?
Yes — structurally. Hapily can produce attribution reporting, but only if you've built the workflows and calculated fields manually. Events OS runs four-layer attribution (Registration → Contact → Company → Deal) automatically on every event completion with zero configuration. Teams migrating report that attribution accuracy improves (because fewer manual workflow steps means fewer configuration errors) and time-to-report collapses (from custom report building to dashboard lookup).
Can I try Events OS before cancelling Hapily?
Yes. Events OS Starter includes a 14-day free trial with no credit card required. Install via OAuth in 3 minutes, run alongside Hapily during migration, only commit to a paid tier once you're satisfied.
