Обновите экспресс 2012 года TFS в экспресс 2013 года TFS

After getting no responses that I thought were valuable I decided to cross fingers and go all the way and guess what:

Upgrading TFS 2012 express to TFS 2013 express is supported and very well I may say.

In my opinion there is no clear answer on how to do this so here are the steps of what I did:

1. First backup all the TFS databases using the TFS utility or SSMS.
2. Download the TFS 2013 express ISO and start the installation. At this point it is a bit scary because the installation starts at once without asking anything about an existing installation or saying anything about upgrading.
3. When this wizard completes you will get the configuration wizard of the new TFS and your previous TFS non functioning. Don’t worry about this. In this wizard select the upgrade option.
4. Here you need to confirm that you have backed up your databases. There is also a link to start a utility that will backup your databases in case you didn’t.
5. By clicking next there are a few more details to fill in and the wizard starts by upgrade your SQL Server to version 2012 and then upgrading the rest of the TFS and your databases.
6. Finally you have a successful completion notice together with a URI for your new TFS and everything working fine, at least in my case they did.
