New to NC, stuck at the occ upgrade error



Hi All

Moving from OC to NC, reusing the /var/www/owncloud directory but replaced all the files & folders with NC13.0.2 files and folders.

The only items that I retained are the config.php file and the .well-known which I placed back into the new NC.

Trying to run the following:

root@mail:/var/www/owncloud# php ./occ upgrade
The process control (PCNTL) extensions are required in case you want to interrupt long running commands - see
Nextcloud or one of the apps require upgrade - only a limited number of commands are available
You may use your browser or the occ upgrade command to do the upgrade
Set log level to debug
Exception: Updates between multiple major versions and downgrades are unsupported.
Update failed
Maintenance mode is kept active
Reset log level

Any help would be greatly appreciated

From which version of ownCloud are you trying to migrate?
