Use caution when working with the below product functionality. Always create a backup of your data before proceeding with advanced solutions. These steps require knowledge of database engines and application databases (DBs) used by your Sage product (including Microsoft/Transact SQL, Pervasive SQL, or MySQL, etc.). Customer Support is not responsible for assisting with these steps and cannot be responsible for errors resulting from changes to the database engine or DBs. Before making changes, backup all system and application DBs required for a full restore. Contact an authorized business partner or DB administrator for assistance.


The error message will appear on a SQL parallel/upgrade on same server.


  • Make sure both the Source and Target SQL Server Service are running with the ‘Local System’ or Domain Admin account
  • Based on the error message, create a folder location that matches the one indicated in the message.
  • Place MAS_System.bak file in that location.
  • Run Parallel Migration once again.
