Hi Experts
I have 2 DB server PROD and DR running in sql server 2008R2 service pack 2. There is a DB mirroring between PROD and DR.
Currently we are planning to upgrade both servers to sp3. As it is service pack upgrade it fixes the bugs which found in earlier version.
During upgradation wht checklist i have to consider and is it better to upgrade both the server separately like first i will upgrade the PROD server and then DR server or is it better to upgrade both in one go.
Thanks
