i have an old owncloud server updateed to nextcloud 12.1.
Now i want a clean nextcloud 13.
So my question is, how do i transfer the data from nc12 to nc 13?
In best case there are no lost users and data. Is it possible?
My hoster is all-inkl, so i have no root access and i have no knowledge with ssh. I only use FTP for filetransfer and for updating my nextcloud.
I hope there is a solution for newbies like me!
