Cause

The source installation has a corrupt SY_Console.M4T file.

Resolution

Try to view SY_Console.M4T file in Data File Display and Maintenance from another install (2020 will not launch after failed migration) to confirm if records are bad.
Create new SY_Console.M4T file in the older version’s \MAS90\MAS_SYSTEM folder.
- - The file can be renamed and the older version launched to create new SY_Console.M4T file.
Once file is recreated, relaunch the migration via the 2020 \MAS90\Migration\migrate.exe (run as administrator).
