Wrote this blogpost in May when attending the Microsoft Ignite Conference in Chicago.
Should have been posted then, but I still think it’s relevant 🙂
As you all know, the Skype4B server upgrade can be done as an in-place upgrade from Lync 2013. However, there are things to consider.
If the server is a Lync 2010 server, there is no way to do an in-place upgrade. Migration is the only way.
Lync 2013 supports the in-place upgrade as long as you can schedule downtime because the services are removed during the process.
When it comes to the server OS, you would want to concider upgrading the server if you’re on WinSrv 2008 or 2008R2. The Skype4B server install will upgrade windows fabric to the latest version, but only on 2008R2.
Recommendation: Win2008 or 2008R2 should be upgraded to 2012R2.
Implication: The upgrade process to Skype4B will have to be done as a migration if your servers are on Win2008 or Win2008R2.
