Practical guide

Move booking systems without running two conflicting calendars

Last materially reviewed 2026-09-23

Quick answerChoose one booking source of truth, preserve future commitments and switch the public route only after the new configuration passes its essential tests.
What to know

Inventory the current commitments

Before changing systems, identify future appointments, recurring series and unresolved requests using authorized records. Preserve the information needed to honor them, but do not export unnecessary personal data into ad hoc tools. Decide which system remains authoritative during preparation. The new scheduler should not begin accepting the same capacity while the old one continues independently, unless a deliberately tested coordination process prevents conflicts between them.

What to know

Separate configuration from migration

First build the new service, staff and resource model using fictional cases. Validate the essential collision, cancellation and rescheduling behaviors. Only then plan how existing commitments will be represented. This guide does not promise an automatic import tool or lossless data transfer for any merchant. If a required field or recurring rule cannot be carried over faithfully, document the limitation and choose an assisted process rather than silently changing the customer’s appointment.

What to know

Make the public switch observable

List the actual entry points: website buttons, embedded forms, profile links and saved customer instructions. Choose a controlled time to change the relevant routes, then verify the destination and booking context. Preserve a way to return to the prior public route if the new one fails, while remembering that switching a link does not undo appointments already accepted. Recovery must reconcile commitments, not merely restore an older-looking page.

What to know

Close the duplicate-booking window

After cutover, check that the old route cannot independently accept conflicting appointments under your chosen process. Do not delete historical records just to simplify the view. Monitor the first genuine bookings for agreement between the public confirmation and staff understanding. Keep a clear owner for unresolved cases and a short record of what changed. A successful migration is a dependable appointment workflow, not simply a new scheduler appearing on the website.

Test the last available resource and a non-conflicting request; accepting everything and blocking everything are both failures.
