Rolling Back Data to Your Previous Release

In certain situations, you may need to roll back your company data after you have migrated to a later version of Tally.ERP. Rolling back data means transferring your data back to the old version of Tally.ERP 9.

Note: Rolling back data after migration may cause data loss or alteration, if any changes have been made to the migrated data. This includes creating, modifying or deleting any transaction, master or report. For example, if a transaction is passed in Tally.ERP 9 Release 5.0 after migration, rolling back may cause loss or alteration of the transaction.
