Core Differences: ERP 9 vs. TallyPrime

|---|---|---|
| Interface & Navigation | Keyboard-driven character layouts with green/yellow styling. Mouse clicks are unsupported. | Modern graphical user interface (GUI) with mouse support and Windows-standard menus. |
| Global Search | Requires memorizing complex navigation paths (e.g. D-A-L to view ledger reports). | Global Go To (Alt+G) search bar. Access any report or voucher creation screen instantly. |

Step-by-Step Data Migration Guide
Follow these steps to migrate your legacy Tally.ERP 9 company data to TallyPrime safely:
Generate Legacy Data Backup
Open your company inside Tally.ERP 9. Go to Alt+F3 > Backup. Specify a destination folder, select your company (typically a 5-digit number folder like 10000), and export it. Keep this original backup safe.
Open Data Folder in TallyPrime
Launch TallyPrime. Set the data directory path to point to your old Tally.ERP 9 data folder. In the company select list, TallyPrime will highlight your legacy company with a red label: Migration Required.
Run Database Conversion
Highlight the legacy company and press enter. TallyPrime will ask if you want to back up before migrating (always select yes). Click Migrate (R). TallyPrime will convert the files and open the Gateway of Tally.
Troubleshooting Common Migration Hangs
- Migration Fails/Hangs: If your database contains corruption, the migration process can crash. To resolve, open the company in Tally.ERP 9, press
Ctrl + Alt + Rto run a rewrite audit, and re-attempt the migration in TallyPrime. - TDL Compatibility issues: Custom TCP plug-ins built for Tally.ERP 9 may crash TallyPrime. Disable all custom scripts in your
tally.inifile before running the migration, and update them separately. - Mismatching Trial Balances: Post-migration, run the Trial Balance report (Display > Trial Balance) in both ERP 9 and TallyPrime. Compare opening balances and final figures to ensure transaction accuracy.
Automating Post-Migration Data Import
If you are moving from Tally.ERP 9 to TallyPrime, you should also digitize your data input workflows. TrulyInvoice eliminates manual voucher entry by reading bank statement PDFs and invoices directly, sending the transaction files to TallyPrime over local Port 9000 securely.
