• @prowlermax,

    I have not upgraded a Cluster to SQL2008R2 yet. I should upgrade a SQL 2005 to SQL 2008R2 in the next two months and my plan is to:

    1.Full system backup backup of the passive node

    2.Upgrade SQL in the passive node

    3.Take a last Full backup of databases in their 2005 version

    4.Failover from SQL 2005 (active) node to upgraded SQL2008R2 node

    5.DBA Check / User Acceptance Checks

    6.Upgrade the now passive SQL2005 Node

    7.Take a full backup of the databases

    8.Failover to the newly upgraded node

    9.DBA Check / User Acceptance Checks
