In-Place Upgrade of Server 2012 to 2012 R2 running CRM 2013

Hello,

we run CRM 2013 with the newest updates on Windows Server 2012. With Updaterollup 2 Version 6.0.23 it does support Windows Server 2012 R2 and because it is the only 2012 OS in our environment we want to upgrade this VM.

It would be nice to do an inplace upgrade of the server OS, so we don't have to install CRM 2013 again and configure it.

Are there any documentation or experience of upgrading the server OS which runs the CRM server?

Best regards

Burak
