As per the title of the discussion, i have Teamcity 5.1.3 installed on Windows Server 2003 (32bit) and running using the HSQLDB for evaluation purposes. I now need to set up Teamcity (5.1.5) for production on Windows Server 2008 R2 (64bit) with SQL Server 2008 R2 as a backing store. I've read through the documentation and scenarios under "Installation and upgrade" in the online documentation but i can't see exactly how i would achieve what i have to do. I don't think the maintainDB script would do a full automated migration (although i might have understood wrongly). Maybe the only way is the manual backup and restoration but again not sure exactly which steps i should follow and in which order. Could somebody please advise as there are many months worth of work set up in the evaluation version and i would hate to loose all the work.
