Before I ask my question I want to mention that I know in place upgrades of Windows installs are generally discouraged but we have a reason to do it thus my question;

Has anyone ever performed an in place upgrade of their OS with Sage 300 CRE on the system.  Have there been an issues (assuming OS ok)?  We have a convoluted situation with Sage 300 17.1, DM, MyAssistant, hh2, and Textura ALL installed and syncing on the same system.  Doing a migration to a new box would feature extensive downtime possibilities and is fraught with many calls to tech support.  An in place Upgrade of Windows from 2008R2 to 2012R2 solves it all including keeping the host name the same for MyAssistant Licensing and hh2 syncs.  I understand the SID would change. 

I also understand DM is at the end of the line.  We will be moving to Paperless after this migration/upgrade is complete.

Thanks
