Data file Damaged after upgrade from 2012 to 2018

[Michael Scholz]

Ok you use Patch5, so I would suggest installing version 2012P8 first. Normally nothing bad should happen but I would also suggest to do a backup of the SQL database before doing anyting.
Get the program version here: https://d2l2g77p7dyozs.cloudfront.net/ASG-RD2012_P8.zip. You can use the 2018 license if your old 2012 license is not adequat for use with 2012P8.
If 2012 works fine then you could again try to import that database by the Migration Wizard of ASG-RD2018.

Best regards,
Michael
