Introduction

Shifting your Tally software and data to a new computer is very common when you upgrade systems or change office setups. But the process must be done correctly to avoid data loss, licensing issues, or errors.
The good news is—moving Tally (ERP9 / Tally Prime) to a new computer is simple if you follow the correct steps.

This article provides the complete, easy, safe procedure for transferring Tally and all your company data to a new PC.

Step 1: Take Backup of Your Tally Data on Old Computer

Before moving Tally, always take a complete backup.

How to take backup:

1. Open Tally
2. Go to Company Info
3. Select Backup
4. Choose the source folder (usually C:\Tally\Data)
5. Choose the destination folder
6. Save

Your backup folder will contain all your company data.

Step 2: Copy the Data Folder Manually as Extra Safety

Along with the backup, copy the original Data folder manually for double-protection.

Location:

Normally Tally data is stored here:

C:\Tally\Data

Copy the entire Data folder and paste it into a USB drive or external hard disk.

Step 3: Install Tally (ERP9 or TallyPrime) on the New Computer

1. Download TallyPrime or ERP9 setup from the official website
2. Install it normally like any software
3. Open Tally on the new computer
4. Skip company selection for now
5. Keep Tally open at the main screen

Step 4: Paste Your Data Folder into the New Computer

Now move your copied Data folder to the new computer.

Paste here:

C:\Tally\Data

If the folder does not exist, create it manually.

Step 5: Change Tally Data Path (If Needed)

If your data is stored somewhere else:

1. Press F12 (Configuration)
2. Select Data Path
3. Browse and select the correct folder
4. Save

Now Tally will read data from your preferred location.

Step 6: Restore Backup (Optional But Recommended)

1. Go to Company Info → Restore
2. Select your backup folder
3. Restore it to the Data folder

This ensures data integrity and removes errors.

Step 7: Reactivate Your Tally License on the New Computer

If you are using a single-user Silver License, you must reactivate it.

Steps:

1. Open Tally on the new PC
2. Go to Help → Licensing → Activate License
3. Enter your Tally Serial Number, Registered Email, and Security Code
4. Tally will activate your license on the new computer

For Multi-User (Gold License)

Just plug in the Tally dongle or ensure the license server is running in network.

No need to activate again.

Step 8: Check If All Companies Are Visible

Go to:
Select Company → Load Company

You should now see all your migrated companies.

If not:

• Re-check data path
• Ensure folders have proper numeric company codes
• Re-copy data if needed

Step 9: Verify Company Data

Open each company and check:

• Day Book
• Trial Balance
• Stock Summary
• GST reports
• Outstanding reports
• Sales/Purchase registers

Everything must match your old computer records.

Step 10: Delete Tally from Old Computer (Optional)

Only do this if:

• Your license is activated successfully on new PC
• You no longer want to use the old system
• Data is verified completely

You can uninstall Tally safely.
