You can use Kentico Xperience Installation Manager to uninstall Kentico Xperience instances, including their project folders in the file system, websites in IIS, and databases on a database server.
Select the instance (or multiple instances) that you want to uninstall and click Uninstall on the main toolbar.
Click Next.
Choose which parts of the installation you want to uninstall:
file system – deletes the instance's project folder and files, the Scheduler service (if installed), and diagnostic tools (event log sources).
IIS – removes the instance's websites from IIS. If the website is installed in a custom application pool not shared with another website, the pool is deleted as well.
database – removes the instance's database from the database server.
remove instance from list after successful uninstallation – unregisters the instance from KIM so that it is no longer visible in the managed instances list.
Click Uninstall.
KIM displays a log, showing the progress of the uninstallation.
