ASG 2015 upgrade 2012 error

[DevOma]

Is it possible that you send me your old database as a backup file? For friday Patch3 is planned and I would like to find this issue before - please send to asg.rd@asg.com - and please add a link to this thread - if it is too big to send perhaps you can upload to a cloud drive and send me only the link

Backup your old database with MSSQL Management Studio and tell me the version of SQL Server you are using...
