You don't want to re-run migration. As long as the company codes are different, you may be able to just copy the MAS_### folders into 2020's MAS90 and run company conversion... You'd have issues with misaligned UDF's (if there have been any changes), and you won't get system level settings like paperless records, but for archive company codes I doubt that's a concern.
Or just set up MAS90 mode shortcuts to the v2017 path and let them access the data without converting to v2020.
