Update Confluence from 6.15.2 to 7.2.0

[roru2k20]

Good morning to all,

Is there a chance to update an app manually, e.g. Confluence from 6.15.2 to 7.2.0?

My first shot was to download in a terminal the current version into tmp-directory and install the *.bin-File, but Confluence doesn't find any "normal" install-directory.

Thanks for any help!

Best regards, Axel
