Old reservations not syncing after a PMS switch
After switching to a new PMS, you may notice that old reservations are not sent to your new PMS when changes or cancellations are made. This may be a temporary issue, but you should check all old reservations to ensure your inventory is up to date.
To avoid manually updating changes and cancellations, ask your new PMS support team if they can import previously created bookings and process channel reference codes.
If your PMS can import bookings:
Contact our support team and request a CSV file containing your platform's bookings.
Send this CSV file to your PMS support team.
Ask your PMS support team to import the file into their system.
If your PMS cannot import bookings:
Manually process all unsent changes and cancellations in your PMS to ensure that inventory updates are sent to your platform and connected channels.
💡 The CSV file contains channel reference codes—three-letter codes indicating which channel a reservation originates from. Some PMS systems can associate this code with a channel by entering a parameter such as "External Reservation ID Number" (or another name depending on your PMS).
