How to check and fix invalid characters:

1. Open your QuickBooks Desktop company file.
2. Check the Company Name:
   ○ Go to Company → My Company.
   ○ Remove any symbols like : , !, @, #, %, ^, &.

   ○ Items/Products: Go to Item List and remove any special symbols.
4. Save your changes.

Tip: Even a single symbol like : or @ can stop migration. Make sure all names are corrected before trying again.

2. Open your company file.
3. Go to File → Utilities → Condense Data.
4. QuickBooks will ask you to backup your file. Always make a backup and save it somewhere safe.

Tip: Condensing does not delete your active data. It only removes old transactions that are already processed.

After completing these advanced steps:

• QuickBooks should be repaired and ready for migration.
• Problems with file size and invalid characters should be fixed.
• If migration still fails, you can contact QuickBooks Support at 1-800-441-3608 or try the special migration link for older versions.
