Is there any risks of upgrading our SQL server 2008 R2 from SP2 to SP2

Question

We have the following settings insdie our farm :-

• SharePoint Enterprise server 2013, on separate windows server 2008 R2 VM.

• SQL server 2008 R2 with SP2, on separate windows server 2008 R2 VM.

now we want to install SQL server 2008 SP3 inside our sql server. so the sql server DB will be upgraded from SP2 to SP3? so is there any risks of doing so ?

Answer 1

There is no risk to applying the SP3 on the SQL server 2008. But you have to plan it.I would apply the patches in the following order.

• Schedule a Downtime for the SharePoint
• I will stop the IIS & timer services so that no connection should make to SQL server while patching. (In one of farm I shut down the server)
• Apply the Patch to SQL server, test and verify it.
• Bring the SharePoint Server back online.
• Test it.

I would not do this one directly from Production, I will test it in the Test environment 1st.
