On an upgrade to 2017.2. it found a previous version, do I "Uninstall previous version?"
On an upgrade to 2017.2. it found a previous version, do I "Uninstall previous version of Teamcity" or not? I don't want to lose my configuration stuff but why is this an option? What if I say no?

Hi Jennifer,
to upgrade using the installer, please follow the procedure described here: https://confluence.jetbrains.com/display/TCD10/Upgrade#Upgrade-win
As you can see there, the uninstaller will get rid of the installation folder, but not of the data directory. Your projects, build configurations, etc are stored in the data directory, so they should be kept (they will need maintenance upon first start, though). There are some important data on the old installation folder that will usually get deleted:
-Any changes done to the configuration files manually.
-The current logs of the server (not the build logs, just the server logs)
-The JRE version bundled with the server, in case you changed it
So you might want to back those up before upgrading. If you are still using the internal database, that is also stored in the data directory, so you shouldn't need to worry about its contents, but if you are still using the internal one, please consider switching to an external database, as the internal one is only meant for test purposes.
