1. Shutdown TeamServer
2. Backup your data and configuration
Please backup $HOME/.BuildServer directory and previous installation of TeamServer.
3. Unpack archive with new build into a directory
4. Go to the AlbusTomcat/bin directory and run command runAll.bat (or runAll.sh under Unix)
5. After start, point your browser to TeamServer's location (e.g. http://localhost:8080/)
You will be presented with a login page. If there were user accounts configured in the $HOME/.BuildServer/config/build-server-config.xml file you can use their id attribute value as username and password. Otherwise click "Register a New User Account" link on the login page to create a new user account.
This version also supports NT domain authorization, see more on this in the TeamCity FAQ.
