We want to upgrade from TeamCity Enterprise 4.0.1 (build 8171) to Enterprise 5.1.2. Our current configuration uses the default method for data storage. We want to use SQL Server 2008. Ideally, we would like to install the new 5.1.2 version on a new server and load the data from the old version to the new using SQL Server 2008 and then decommission the older version. What is the best procedure to accomplish this?
