Determine what is being transferred
Active and future reservations, guests, rooms, types, prices and open financial items do not have the same priority or format. Each group should be specifically checked.
Create test import
Before final migration, check a sample of reservations, dates, rates, room assignments and contact information. Document and resolve differences before cutover.
Plan the cutover day
Define who stops the entry into the old system, who does the final export, who confirms the new system and how changes are recorded during the transition.
Preserve the ability to verify
The archive or controlled access to old data remains accessible according to hotel policy and legal obligations.
