Migration tool - owncloud 8.2.7 to latest nextcloud version

Migration tool - owncloud 8.2.7 to latest nextcloud version

Hi Guys,

I would like to upgrade an existing and proper running owncloud 8.2.7 () version on a 4.1.0-ucs190-amd64 platform:

root@www:/var/www/owncloud# dpkg -l | grep owncloud
ii owncloud 2016.8.2.7-enterprise-0 all cloud solution for data and file sync, share and view
ii owncloud-meta-8.2 8.2.7 all Meta package for ownCloud 8.2

root@www:/var/www/owncloud# uname -a
Linux www 4.1.0-ucs190-amd64 #1 SMP Debian 4.1.6-1.190.201604142226 (2016-04-14) x86_64 GNU/Linux

Fortunately, there are no additional apps which are installed.

My intention as first step will be to upgrade this owncloud instance to the latest nextcloud version. I intent to use the nextcloud migration tool. The migration tool is clearly mentioning that it is possible “This tool supports ownCloud 8.2 to ownCloud 10, migrating to the appropriate Nextcloud release automatically.”

My questions are:

  1. Have anyone experiences by migrating from an older version of owncloud to nextcloud using the migration tool?
  2. After the migration and facing issues can I revert the applied changes by the migration tool?
  3. Are there other suggestions/recommendations to migrate to latest nextcloud version?

I am really looking forward to get feedback,


Latest migrations were probably from more recent versions. The migration script is reviewed from time to time but I can’t say if it works for oC 8.2.

No, even for major upgrades in oC and NC this is/was not possible. Please make a full backup, this is the only way to get a reliable system back in case it goes wrong.

After the backup, you can try the migration tool, it should bring you to NC 9.0. If not, do it like a manual upgrade (keep data/ and config/ folder, delete all the other files, put the code of the new version from nextcloud.com/changelog, run the upgrade process via sudo -u www-data php occ upgrade). Then go step-by-step through all major versions. NC 9 -> NC 10 -> …

The update app gets more reliable after NC 11 I think, then you can start it easily through command line (from within your Nextcloud folder):

sudo -u www-data php updater/updater.phar

Many thanks for your detailed reply and will do it as you have suggested it.

  • Full Backup
  • Migration tool (if it does not work applying a manual installation of NC 9.0)
  • Upgrades of NC 9.0 --> 10.0, 10.0 --> 11.0, 11.0 trying to apply updater/update.phar

Many thanks and have a great day ahead.
