Hello,
I have a two node cluster (sql server 2008). I would like to upgrade to SQL Server R2 and at the same time would like to patch to Service Pack 3. What would be the best way to accomplish this task with minimal downtime to the users?
This is my plan:
1. Detach any read only databases.
2. Upgrade to 2008 R2 (shared feature only) on passive node (node1).
3. Apply SP3 on passive node in step 2.
4. Swith active node to passive node (node2).
5. Upgrade to 2008 R2 (shared feature only) on node2.
6. Apply SP3 on node2.
7. Upgrade db (instance) on node2 to 2008 R2.
8. Upgrade db (instance) on node1 to 2008 R2.
9. Re-attach read only databases.
Is my procedures correct?
Thank you.
