I am running desktop central on a Windows server 2008, and I am planning to upgrade it to the 2019 version, but in order to do that I am obliged to delete some files from the disk where Desktop Central is installed,

my question now is which kind of files or directory can I delete that will not affect my system.

I want directory on this path: C:\ManageEngine\DesktopCentral_Server\webapps\DesktopCentral

Many thanks
