Updating

DaCollector stores application binaries and server data separately. Update the binaries without deleting the data directory unless you intentionally want a clean instance.

Installer Updates

1. Stop DaCollector.
2. Back up C:\ProgramData\DaCollector.
3. Download the newer DaCollector.Setup.exe.
4. Run the installer.
5. Start DaCollector.
6. Open http://127.0.0.1:38111/webui and confirm the server loads.

The installer is configured to uninstall the previous installed app before installing the new files.

ZIP Updates

1. Stop DaCollector.
2. Back up the data directory.
3. Extract the new ZIP to a new application folder.
4. Start the new DaCollector.exe.
5. Confirm it uses the expected data directory.

If you run multiple ZIP builds side by side, set DACOLLECTOR_HOME explicitly for each instance.

Rollback

1. Stop DaCollector.
2. Restore the previous application folder or reinstall the previous installer.
3. Restore the backed-up data directory if the newer version performed database migrations you do not want to keep.
4. Start DaCollector.

Always keep a data backup before testing a build from a different branch.
