Here’s a quick reminder from Sage.
When upgrading MAS90 or MAS200 to their new version 4.4 remember that the migration utilities must be used. This is so that your system files are properly copied into the new company.
You cannot migrate data once and then simply copy over any system files as you may have done in the past. Using the migration utility also means that you’ll be copying back over system files that contain UDF and Paperless Office information.
Plan ahead for testing on these areas. When needed for larger jobs you’ll probably have to export and import UDF (user defined fields) or the migration utility will write over any changes you’ve made.
