Changing Database Compatibility

  • Does changing the database compatibility from 2000 to 2005 require any downtime or interruption to service? I need to do this without causing any interruption or affecting applications.

    Thanks!

  • You can change the compatibility level with connections in place. But according to the Books Online, if you do that, you could get incorrect results in queries or other odd behavior. I'd plan for some downtime, just in case. Kick everyone off, take a backup, then change the compatibility level. That way, if things go south, you're in a good position to recover.

  • To be safer even still I'd run the Update Stats routine after you change compatability.

  • Great, thanks to both of you for the help!
