Quick SQL Upgrade question. Currently I have SQL 2008 running on 2 servers. They both read from the same SQL database the runs off an attached storage. Both currently are using the trial 180 day license. I have since purchased the license which is actually a download ISO and have it in both server DVD drives waiting. My question is can I upgrade the license while in production without having to stop anything? I just want to make sure I dont bring anything down while doing this as these are now in production. I just want to make sure SQL just doesnt stop working as its close to the 180 trial limit. Thanks for your answers.
