Everyone plans a migration forwards. You evaluate the new platform, you like it, you plan the build, you set a go-live date. Almost nobody plans it backwards, which is the direction the risk actually runs. The new platform will be fine. The question that decides whether this is a two-month project or a six-month one is what you can physically get out of the system you are leaving.
The evidence that this is hard is not subtle. Only 4% of event leaders say pulling their event data is easy.1 That is a statistic about people using their platform normally, with a support contract and no deadline. Now imagine doing it once, completely, under notice.
Why the exit is the hard part
Platforms are built to be excellent at getting data in and merely adequate at getting it out. That is not usually malice. Import is a feature people evaluate before buying; export is a feature people need once, at the end, when they are already leaving and no longer worth optimising for.
The result is a predictable pattern. Registration records export cleanly, because that is the obvious thing. Everything downstream of registration exports partially, in a different shape, or as a report rather than as data. And the further a piece of information sits from the attendee record, the worse its export story tends to be.
The seven things living in your platform
Write these down and find out, specifically, which format each one comes out in. "We can export your data" is not an answer to this question.
Two of these deserve special attention. Unsubscribe records are not a nice-to-have: carrying a fresh list into a new platform without the opt-outs attached means emailing people who told you to stop, which is a compliance failure and a reputational one. And session-level check-in history is the substrate under accredited education. If you issue CME credits, that history is the evidence behind every certificate you have ever sent.
Test the export before you give notice
The single most useful thing in this article: run a full export while you are still a happy customer with a live support contract, months before you intend to move. Not a sample. The whole thing.
You are checking three things. Does every one of the seven categories come out, and in what format. Does the data survive a round trip, meaning can it actually be read and imported by something else. And how long does the export take to produce, because a support ticket that takes three weeks during a normal month will not take less during your notice period.
Whatever you find, you will find it while you still have leverage and time. Teams who skip this step discover the gaps on the day they are trying to close the account, which is the worst possible moment to be negotiating.
The three clauses that decide your timing
Your migration date is usually set by your contract rather than by your project plan. Three clauses do the deciding.
The billing commitment. Annual billing with a minimum is standard in the mid market: published 2026 pricing shows Bizzabo starting at $17,999 per year on a three-user minimum, billed annually.2 That sets the earliest date at which leaving makes economic sense. Above that tier, Cvent, Splash and Whova publish no rates at all,2 which means your exit terms are whatever your particular contract says and nobody else's experience will tell you.
Auto-renewal and its notice window. This is the one that actually catches people. A renewal that rolls automatically unless cancelled thirty or sixty days out means a week of hesitation can cost a full year. Find the date, put it in a calendar with a reminder a month ahead of it, and do that today rather than when you start evaluating.
Post-termination data access. How long can you still reach your records after the relationship ends, and in what format. For reference, our own terms commit to keeping your data available for export for 30 days after termination in CSV or another standard, machine-readable format. Whatever your current vendor's number is, know it before you give notice, because that window is when the seven-item checklist above has to be completed.
Where in the calendar this belongs
Immediately after an event, never before one. The reasoning is simple: you want maximum runway to the next set of doors opening, and you want the outgoing platform still live and supported while you verify the incoming one.
The strongest version of this is to run both across one real event. Take registration on the new platform while keeping the old one accessible in read-only form, so that if anything is missing you find out with a fallback still available rather than at a check-in desk. Setup on a new platform typically runs two to four weeks, which fits comfortably in the gap after an event and badly in the month before one.
There is a strategic version of this decision too, which is whether you are moving to one platform or continuing to stitch several together. We took that apart properly in the complete event tech stack for 2026: a quarter of large enterprises run six or more event tools at over $250,000 a year, and only one in five has connected them to anything.3 If you are going to the trouble of a migration, it is worth asking whether you are moving one box or collapsing several.
Where Aurentex sits
Two things are worth saying plainly, because this is an article about leaving platforms and we are a platform.
First, on the way in: we import from your existing system as part of setup, including bulk import of up to 10,000 guests from a spreadsheet, and setup runs two to four weeks with a test event before your first real one. That is the point at which the seven-item checklist gets used, so bring it to the first call.
Second, on the way out: your attendee data is yours, exportable in full at any time during your subscription, not only at the end, and our terms commit to a 30-day export window after termination in CSV or another standard, machine-readable format. This matters more than it sounds. Under India's DPDP Act you are the data fiduciary for your attendees' data, which means the obligations to produce, correct and erase records sit with you, and you cannot discharge an obligation for a record you cannot reach. We wrote the full checklist in our DPDP compliance guide.
We would rather compete on whether you want to stay than on whether you can leave. Your first event on Aurentex is free, which is the version of that sentence with something behind it.
Common questions
What data should I export before leaving an event platform?
Seven categories: attendee and registration records with all custom fields, session and check-in history, email history including unsubscribes, financial records, design assets, configuration, and reports as data rather than PDFs. Most teams remember the first and are surprised by the rest.
When is the best time to switch event management software?
Straight after an event, never in the run-up to one. Run both platforms across one real event if you can, with the old one read-only as a fallback. Setup typically takes two to four weeks, which fits the gap after an event and not the month before one.
What contract terms make it hard to leave?
Annual billing minimums, which set the earliest sensible exit date; auto-renewal notice windows, which punish a week of hesitation with a year of fees; and the post-termination data access window, which is how long you can still reach your own records. Find all three before you give notice.
Is exporting attendee data a compliance requirement in India?
In practice yes, because of your position rather than your vendor's. Under the DPDP Act the organiser is the data fiduciary for attendee data, so the duties to produce, correct and erase sit with you, and you cannot discharge them for records you cannot reach.4
