I have two running Owncloud systems which Iāve tried to migrate to Nextcloud using the manual migration process:
version 9,1,2,5 went beautifully
version 9,1,8,2 fails with the following error message when I run this command āsudo -u www-data php occ upgradeā:
An unhandled exception has been thrown:
OC\HintException: [0]: Downgrading is not supported and is likely to cause unpredictable issues (from 9.1.8.2 to 9.1.6.1) ()
Iāve followed the instructions on this page https://docs.nextcloud.com/server/12/admin_manual/maintenance/manual_upgrade.html and using the reference on this page https://docs.nextcloud.com/server/13/admin_manual/maintenance/migrating_owncloud.html
Iām trying to use the 10.0.x Nextcloud download as the first step.
Any thoughts? Please. Many thanks.
