Migration failed from OwnCloud 10.6.0

I’ve tried to migrate from owncloud 10.6.0 to nextcloud, but in all cases (migrator and manual installation) I got the error “Exception: Updates between multiple major versions and downgrades are unsupported.
Update failed”

What can I do?

Afaik only a migration from ownCloud 8.5 to 10.5 is currently supported. You might try to change the version ownCloud version number in your configuration to a 10.5 one, but as usualy you will do this on your own risk :wink:

here it was said that a manual upgrade from owncloud 10.6 to nextcloud 21.rc2 worked without problems:

Migrate oC10.6 to Nextcloud21

were there still big changes between rc2 and the release?
