In your case I would write a script to automate as much of this process as possible. The clients I manage are Windows based, so I wrote a VBScript that upgrades ownCloud to Nextcloud and automatically copies the configuration. I’m sure a linux/mac script would be similar.
All my clients are Windows users, well 98%, but I don’t want to use a script, cause I really want the users to do this themselves, but I can’t present a script to them. I would rather like the Nextcloud download to automatically replace owncloud, that is, removing owncloud and using its configuration file, atleast as an option when installing
I think I understand. I’m not sure how a script is any more difficult to execute than an exe, but the way I have it set up is that you drag the Nextcloud installer on top of the vbscript, and it takes care of the rest. So basically a one click process, couldn’t get much easier even if it was built into the installer.
I would share the script here, but I need to spend a little time removing confidential business info from it first. Maybe tomorrow
