Migrate to the Latest Release | From Tally.ERP 9 Release 5.0 – TallyPrime 2.1
Before migrating your data to the latest release, follow the best practices for a seamless data migration experience.
While migrating, you will experience the following:
- The original 5-digit company is saved as a folder for reference. You can rename it and access data using the previous release if needed.
- Data gets migrated to a new 6-digit company in the latest release.

If migration takes hours due to large data volume, you have the option to:
-
Stop migration now and resume the process anytime later.
-
Continue working on the date in the earlier release during migration. Any changes made there will be automatically migrated to the latest release.
