Q 1: What is Tally Data Migration Tool and how does it help?
Answer:
The Tally Data Migration Tool helps in migrating the data from Tally 7.2 to Tally 8.2.
This works with the Tally 8.1 exe and allows you to migrate company data (Masters, Vouchers and Reports). This tool also allows the migration of TCP (Tally Compliant
Product) files.

Answer:
No. Once Tally 8.1 is installed, you will not be able to work with Tally 7.2 data, without migrating the same to Tally 8.1.

Q 3: Can Tally 7.2 data be migrated if there is only a single error?
Answer:
No, data migration will not take place, even if there is only one error during the migration process. In other words, you will not see any partial /incomplete migrated data of 7.2, in the data directory from where you selected to migrate.

Q 4: How do I migrate data from Tally 7.2 to Tally 8.1?
Answer:
If you are an existing Tally 7.2 customer, follow the steps given below:

1. Install Tally 8.1

2. Go to Start > Programs > Tally 8.1 > TallymigrateData. (You can also begin the process by double clicking on tally72migrate.exe file in the Tally application folder).

3. Two splash screens, Tally Data Migration Tool and Tally 8.1 appear.

4. Click the Migrate Data on the Tally Data Migration Tool screen to select the company whose data needs to be migrated from Tally 7.2 to Tally 8.1.

5. Specify /select the data directory in the directory field and select the company from the list of companies.

7. Press ‘Enter’ to accept, and complete the migration of selected company.

8. The status of migration from Tally 7.2 to Tally 8.1 can be seen on the Migration Messages Pane.

9. When the migration is complete, it displays a information pop-up, “migration completed, check statistics (press any key)”, followed by congratulation message in yellow box.

10. If any error occurs during migration, it gets logged into a file ‘migration.err’, which is automatically generated and made available in the Tally application folder.

11. The migrated companies are saved in the Tally 7.2 data folder. The migrated data is prefixed with a ‘0’ and appears as a 5 digit number. For example, if the company folder number, before migration was ‘0099’, after migration it would be ‘00099’.

12. Now, you can start working on Tally 8.1, which has the migrated data.

Note: Ensure that the Tally 8.1.exe and the Migration Tool are in the same folder.
