I had 2 AAC servers connected with the farm information on a SQL 2000 server. Due to end of life I had to migrate the database to a new SQL 2005 server. This is how I did it;

1. I backed up the database (usually called by default the name of your AAC farm) on the SQL 2000 server and restored it onto SQL 2005.
2. Open the AAC Server configuration utility. Go to ‘Services’ and stop all services.
3. Go to ‘Server Farm Information’ and change the name of the SQL server.
4. Restart the services.
5. Check the log/event logs for any unusual behaviour.
6. I bounced the server(s) to be sure.
