In short
A structured migration typically takes 2-4 weeks from first data cleanup to go-live. The four phases are: data audit, cleanup, parallel run and full switchover. The most common mistake is skipping the cleanup.
How long does migration from Excel to booking software take?
A structured migration typically takes 2-4 weeks from first data cleanup to go-live. The four phases are: data audit (3-5 days), cleanup (5-10 days), parallel run (7-14 days) and full switchover (1-2 days).
Phase 1: Data audit
Find out what you actually have. How many active members? How many "active" who have not been in 6 months? Which columns in your spreadsheet are used consistently and which are a mess? Export everything and make a spreadsheet about your own data — you will be surprised.
Take photos or screenshots of all the different places you store things: spreadsheets, paper, calendars, inboxes, sticky notes. You cannot migrate what you do not know you have.
Phase 2: Cleanup
This is the phase most centers skip and regret. It is tempting to import everything 1:1, but that gives you a new system full of old mess.
Delete (or archive) inactive members that should not come along. Standardize fields — is it "PT" or "Personal Trainer" or "Personal Training"? Pick one and clean. Check for duplicates. Make sure email fields actually contain emails.
The investment here pays back tenfold. Every error you do not catch now, you catch after go-live — where it costs ten times as much to fix.
Phase 3: Parallel run
Before you fully switch, run 1-2 weeks in parallel — you handle bookings, payments and member management in both systems. It is annoying, but it is the only way to catch system errors, data issues or flow problems before they hit your members.
Use the period to train your team. If only the center manager knows how the system works, you fall back to spreadsheets the first time they are on vacation.
Phase 4: Full switchover
Pick a go-live day that is not close to a big event or holiday. Tuesday is better than Monday (fewer start-of-week issues) and better than Friday (you have the weekend to recover if something breaks).
Communicate to members in advance. A short email two weeks before, a reminder two days before. Explain what they need to do (typically: nothing), and where they can get help if something does not work.
The three most common migration mistakes
1. Skip cleanup. You import bad data and get a bad new system. Guaranteed embarrassment.
2. No parallel run. You discover problems after go-live, where they are visible to members.
3. No team training. The center manager knows how it works. The rest of the team stores things in spreadsheets "just in case". Within 3 months you are running two systems.
