I’ve had an old version of OwnCloud hanging around and offline. I’ve finally gotten round to trying to sort it out again. It’s version 8 and we’re now on V10. Upgrades between major versions are not supported and there is no way I’m going to upgrade all the way through from 8 to 10. So is there a way to just port the users data?
If you are comfortable losing all your shares - sure. You can just back up the data directory and restore it in a fresh 10.0.10.
But I think ownCloud supports direct upgrade from 8.2.5 to 10.0.10.
