I have a nextcloud installation on an old debian server, currently stuck in version 20.0.11 (cannot upgrade because of outdated PHP version 7.2 as far as I remember) . I plan to move this installation to a new server using official latest docker image.
How should I proceeded at easiest to migrate my installation and convert my data to 25, given that direct migration from 20 to 25 shouldn’t be possible (I read somewhere I should migrate to every major version step by step, right?) ?
Keeping the file history would be nice to have but not mandatory.
Thank you for any advice.
