Install nextcloud with backup of owncloud


id like to switch from owncloud to nextcloud, cause hdd crash and new os installation is the chance to change. i got the /var folder from my old system as backup and like to take the old settings to my new installation. which steps do i have to take to ensure that all setting like users and database are on nextcloud? i guess many folders are the same and i read an migration tutorial, but i depends on an existing system with oc, my os has nothing at all at the moment.

hope you can help me, thanks tim

I found this article on how to backup a minute ago asking myself how I should handle backup/restore, maybe try to reverse the process?

Tell me how it goes!

Good luck!

Well i made a clean new installation, took me some time but now everything is up to date.
thx for your help
