Tally Data Backup 

Migration is the process of changing data to meet the new version. It's a vital stage in the software upgrade process. Data might become useless as a result of failed data transfer. It's possible that this is due to data that hasn't been properly changed. As a result, it is highly recommended to make a backup of important data before updating. 

How to take backup in tally prime?

 The backup process in steps are: 

  1. Select 'Backup' from the drop-down menu under 'Select Company.' 
  2.  Select a firm from the List of Companies.  
  3. Press the 'Enter' key.  
  4. The backup process will begin.  
  5. It will be finished in a few minutes. 

Data Migration from Tally ERP 9 to Tally Prime: 

We are now ready to begin the data migration after a successful data backup. To do so, launch Tally ERP 9 then enter the location where the data is stored. 

Now launch Tally Prime and paste or navigate the same url. It will display a list of all firms in the same way as Tally ERP 9 does. The only difference is that every firm has a "Migration Required" statement next to their company number. 

This implies that you'll need to migrate your data from the previous edition to Tally Prime to open that firm. Simply choose the firm and press enter to migrate. 


It's worth noting that a business may only be utilised in one version at a time. As a result, only one version of business data will be available. It is not possible to use the same business in several versions simultaneously.

The backup will then be requested, along with its route, on display above. If you haven't done so before, go to C: Configure to take a backup and alter the backup path.

By default, the data backup function is set to YES. You can choose to update it if you want to. Select R: Move to commence the migration process once you've taken a backup.

After you've completed this, your firm will appear on the list of organisations, and you'll be good to go because your organisation is now Tally Prime compliant. It indicates that Tally ERP 9 is no longer associated with it.
