Upgrade from Prior versions

Getting a bit more specific, Tally.ERP 9 will migrate all data from Tally 7.2 onwards, without any assistance. If you have an older version (6.3, 5.4 and so on) you will need to bring your data to 7.2 and then migrate (our Sales & Support partners will be able to help you). In any case these tools are available at no extra cost.

In a few cases you might have customised or extended Tally – this would have been done with one or more TDL's, most likely built by one of our partners. Tally.ERP 9 comes with a TDL conversion tool that will attempt to convert such TDL's. Note, the word 'attempt' – since both the product and the TDL language evolve, there is a small possibility that the conversion may not succeed. In such cases you would need to contact the author of the customisation and make the necessary changes to the TDL. We therefore recommend that where customisations exist, there be a simple pilot undertaken to assess impact.
