Migrating TFS

Dave Mason has notes on migrating TFS from one server to another:

If you are migrating, but want to keep the databases on SQL 2012 Express, then you can skip this part. I wanted them moved to my SQL 2014 instance. So I did a traditional backup/restore from SQL 2012 Express to SQL 2014. I took new backups of the SQL 2014 databases, and then uninstalled SQL 2012 Express. Then I had to configure TFS to connect to a different SQL instance. Within the web.config file (%ProgramFiles%\Microsoft Team Foundation Server 12.0\Application Tier\Web Services\web.config), I found an application setting named “applicationDatabase”. I made a backup copy of web.config first, then I changed the “applicationDatabase” value. It should be in a recognizable format if you’re familiar with SQL Server connection strings. You can also make this change within IIS. It was there that I noticed a few other settings that contained SQL connection strings. Check out the following in IIS and change settings as needed:

Dave has lots of screen shots to make the process easier to understand, but my main takeaway is that for the most part, migrating TFS ┬áis a huge pain…
