Hi all
We have a cluster with 2 nodes (Windows Server 2008 R2) and SQL Server 2008 R2 is also installed in cluster mode.
I want to upgrade Windows to 2012, and SQL Server to 2014 on the same servers and storage.
What is the best approach for this purpose with minimum down time?
In this article: https://technet.microsoft.com/en-us/library/dn530781.aspx
I saw that SQL Server cannot be migrated using role migration wizard :(
Any help would be greatly appreciated.
