We have a SQL 2008R2 active/passive SQL cluster running on Windows 2008 R2 cluster.
I would like to add a SQL 2012 clustered instance to the same Winows 2008 R2 cluster.
Are there any issues involved having a SQL 2008 R2 clustered instance running side by side with a SQL 2012 instance in same Windows 2008 R2 cluster?
Are there any pitfalls/"gotchas" to watch for with SQL 2012 cluster install?
Thank you so much!
