Wipe and re-install owncloud 9 and restore files? How to do this?

Hey,

maybe the post below could be interesting for your as well. Personally i would revert to your backup of 8.2, look for the mentioned repository providing PHP 7 and then upgrade afterwards to 10.0.10. This sounds to me like the most sane thing to do.

Upgrade from oc 8.1 to 10.0.10

For the ownCloud side you will need to upgrade to 8.2.latest and from there to 10.0.x … Thats the first version which can skip major versions for the upgrade with database migrations, etc. I would go to 8.2 on the old environment, then do a snapshot backup of both database, storage and config.php. Then install newest CentOS with oC10 on a second machine, get the database and storage connected, and do the upgrade in this test system. Semi packages for 7.2 are perfectly fine.
