I am attempting to upgrade a client from Sage 100 Standard V4.05 to V2017 and when I am migrating the System I am receiving this error during the Post Merge
Prepared failed with the following error: The D/M is invalid... And the Migration exits
I found an article on the SAGE KB that the SY_Griddefinition.m4t might be corrupted and replaced it with clean 4.05 version.
Still blowing up.
Any suggestions?
