Below steps should be followed to assure an unproblematic upgrade to the latest version of TFS4JIRA Self-Hosted.
Before continuing with the below steps, please make sure your environment complies with TFS4JIRA latest version requirements and prerequisites. A detailed documentation page concerning the latest released version can be found in this section: https://confluence.spartez-software.com/display/TFS4JIRA/Installation
In order to be 100% safe from configuration data loss, please backup the database file with the current configuration.
the configuration file is by default present in this folder: C:\inetpub\wwwroot\tfs-jira-synchronizer\App_Data (please look in other/custom location if you performed custom TFS4JIRA installation)
database file name: config.sdf
please copy this file to a safe location, for example, your desktop
Uninstall currently installed TFS4JIRA using standard Windows procedure - 'Uninstall a program' in the ‘Programs’ section of the Control Panel.
TFS4JIRA uninstaller will not remove previous logs and configuration database
Please download and install the latest version of TFS4JIRA. Detailed instruction: https://confluence.spartez-software.com/display/TFS4JIRA/Installing+TFS4JIRA+Synchronizer
Once installed please run the TFS4JIRA configuration page.
the first run always takes longer to load the page
since uninstallation did not erase the configuration file, when you login, all profiles should be present and setup in your TFS4JIRA
If for any reason proper expected configuration is not visible, because due to some reason configuration database has been replaced with a blank version, please simply use the backup created in point 2 and copy it to your current config.sdf location (by default C:\inetpub\wwwroot\tfs-jira-synchronizer\App_Data)
