Hello, I have a few problems with migrating from owncloud 10.3.0:
I tried to follow this guide: https://nextcloud.com/migration/, but got this error message after running the updater and going to the main site:
Exception: Updates between multiple major versions and downgrades are unsupported
The updater tried to install nextcloud 12.0.12. This also has the problem that nextcloud 12 does not support php 7.3, although I could move it to a lower php version temporary for the upgrade.
Is there a different way to migrate from owncloud 10.3.0 to nextcloud?
