I have a server with 2008 R2 SP1 using two named instances. When I run the SP3 upgrade executable (SQLServer2008R2SP3-KB2979597-x64-ENU), do I run this once or twice (one for each instance)? I also realize that I need to run the Meltdown Patch executable, I presume also one time or two times? For my single instance servers, I simply run the upgrade executable. I tried looking for posts on this subject but could not find any. Thanks!!
