How to Switch Booking Systems and Transfer Your Booking Diary (CSV)

Need to transfer your booking diary from one online booking system to another? Switching doesn’t have to mean starting from scratch. In most cases, you can export your bookings (usually as a CSV) and import them into your new online booking system.

Quick answer

• Yes, you can switch booking systems without losing your diary
• Most providers support CSV export/import for existing bookings
• The critical step is validating dates, times, staff, and services
• Use a cutover date to avoid double-booking

Short answer: you can transfer bookings with CSV

The scariest part is often the fear of change. In reality, switching is mostly a data transfer and a careful cutover. If you plan it properly, you can move your current bookings and continue taking appointments without chaos.

For straightforward CSV-based transfers, many businesses can switch in as little as 30 minutes of focused work once both providers confirm the CSV export/import steps (the mapping/validation is the key part).

Step 1: choose your cutover date (when to stop taking new bookings)

Contact your current booking provider (or your current software company) and give them a clear end date for accepting new online bookings. You can choose something like:

• In 15 days time: block booking creation from that point
• In 1 month time: transfer everything at the end of the month
• Any specific date that matches your diary rhythm

The goal is simple: stop new bookings in the old system at the same time you turn on the new system.

Step 2: request the right CSV export (and confirm the format)

Most booking systems support CSV exports, but the columns and formats can differ. Ask for the export that includes the bookings fields your new provider needs.

• Bookings export (start/end dates & times, staff, services, status)
• Client/contact details (if available)
• Cancellation/reschedule history (if your new system can import it)
• Any recurring booking rules (if your current system supports them)

Do not worry if you have “messy” data. The import process is where mapping happens. What matters is that you can export the bookings.

Step 3: confirm CSV import mapping with the new provider

Before you switch, contact the company behind your new booking platform and ask how they want the CSV prepared and imported. The best time to do this is before you export, because it helps you get the format right first.

• Ask what CSV columns they expect (and what can be left blank)
• Confirm how time zones are handled
• Confirm how services and staff are matched (by name, ID, or mapping)
• Ask whether cancellations and reschedules import cleanly

Step 4: export from the old system (how much to move)

Once you have your cutover date, export your bookings up to that point. Many businesses export:

• All bookings for a defined range (for example, the next few months)
• Or the full historical set if they want a complete archive
• Or only the bookings they still need to manage immediately

If your provider can export “all bookings”, that is usually the safest option.

Step 5: import into the new system and validate

Importing is rarely “press one button and forget it”. You should validate what came across:

• Check dates and times: no off-by-one-day or time shifting
• Check staff assignment: bookings should land with the correct person
• Check service mapping: the right appointment type should appear
• Check client details: names and contact info should match
• Check booking status: confirmed vs pending vs cancelled

If anything looks wrong, fix the mapping and re-import (or import a smaller batch first and scale up).

Step 6: block availability and prevent double-booking

During the transition, you want one clear source of truth for availability. Use your chosen cutover date to make sure:

• The old system stops creating new online bookings
• The new system turns on booking creation at the same time
• Staff diaries do not “overlap” in a confusing way

Keep the old system accessible for a short while as an archive. That makes it easier to answer “where did my booking go?” questions.

Step 7: notify clients (if needed) and switch booking links

Depending on your current setup, you may need to notify clients of the updated booking process. At minimum:

• Update any “Book now” buttons on your website and social profiles
• Ensure your confirmation and reminder messages look correct
• Confirm your business hours and booking windows are set properly

Common mistakes to avoid

• Cutting over without validating a sample import first
• Not confirming how staff and services are matched
• Leaving the old system accepting new bookings after the cutover date
• Forgetting cancellations and reschedules (if they matter in your workflow)
• Turning on booking links before the new system is ready

Switching checklist

• Choose the cutover date
• Ask for bookings CSV export (and client export if available)
• Ask the new provider what columns/mapping they expect
• Export from the old system up to the cutover point
• Import into the new system
• Validate: dates, times, staff, services, status, clients
• Enable new booking links at the cutover time
• Keep the old system as an archive for troubleshooting

You do not need to feel stuck. If your booking system is not working for you, export your bookings, plan the cutover date, and transfer everything cleanly to your new platform.
