I finally āhad itā with a bunch of recent ownCloud bugs, and decided to migrate to NextCloud this weekend. Following the migration guide here: https://nextcloud.com/migration/
I downloaded the NextCloud 11.0.3 tarball, followed the steps, ran āocc upgradeā andā¦ failure. āException: Updates between multiple major versions and downgrades are unsupported.ā Fair enough, I fired up the web browser, tried again from the login page for kicks, andā¦ same failure. Mildly frustrating.
Given that, whatās my migration path to NextCloud from ownCloud 10.0.0-1.1?
I think their documentation needs to be updated, but I think you need to go from the latest version of ownCloud to Nextcloud 10.0.x. Then from there you should be able to upgrade to 11.0.x. Let us know how that goes.
No love. Installing Nextcloud 10.0.5 and trying to re-run the upgrade gives me " Downgrading is not supported and is likely to cause unpredictable issues (from 10.0.0.12 to 9.1.5.2)"
Thatā¦ seems like it would be a good thing to have in the documentation, perhaps the āvalid use of the <blink> tagā long referenced in lore and song. Now my owncloud instance is down and I have cranky users. Whatāre we looking at for a release date for v12?
So about 3 weeks, so I suggest you pull out your backup and go on restoring.
And next time do a cross-crade on a mirror server, not on the live one, or migrate manually.
It Works For Me ā¢. Just did it yesterday, it was mostly seamless. There are some Apache modifications to be made (nothing earth shattering), but once those were sorted the usual āocc upgradeā did its thing and everything came up.
As always, YMMV, take and test your backups, etc, etc.
