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 http://php.net/manual/en/book.pcntl.php 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 root@mail:/var/www/owncloud#
Any help would be greatly appreciated
