Tally Prime Data Migration & Backup from Tally ERP 9

Data migration is a very crucial step in any software up-gradation. Before directly jumping into tally prime data migration, first let me tell you, what is data migration. In the migration process, data make necessary changes to make it compatible with the destination version.

But in some cases, if the data is not modified properly or the migration fails then data will become useless. This means it will not remain even compatible with the source version as well as the destination version.

Due to that, it’s always recommended to take a backup of your valuable data before starting an upgrade.

Tally recently launched Tally Prime, a new business accounting management software as a replacement of Tally ERP 9. So today here I will guide you about “How to take data backup and migrate it from Tally ERP 9 to Tally Prime”.

Before starting the migration, let’s discuss the backup procedure for Tally ERP 9.

Tally Data Backup

It’s a very important feature in upgradation, it allows you to take whole data backup as well as you can select company data at once.

So first we take a backup from old Tally. In my case, it’s Tally ERP 9, but it remains the same for all previous versions of Tally. To take backup we need to follow these steps.

1. Go to Select company and Select Backup.


2. Now it will show a panel to select Source Path and set Backup Destination Path. After that, you can select a company from the “List of companies” to take backup.
