Migrating from ownCloud
|
|
=======================
|
|
|
|
|
|
.. note:: Especially when migrating from ownCloud to Nextcloud you should
|
|
create a backup of the config, database and the data directory,
|
|
in case something goes wrong.
|
|
|
|
Currently migrating from ownCloud is like performing a manual update.
|
|
So it is quite easy, to migrate from one ownCloud version to at least one Nextcloud version.
|
|
However this does only work with versions that are close enough database and code-wise.
|
|
See the table below for a version map, where migrating is easily possible:
|
|
|
|
+-------------------+------------------------------+
|
|
| ownCloud | Nextcloud |
|
|
+===================+==============================+
|
|
| 10.11.x | 25.0.x (but at least 25.0.2) |
|
|
+-------------------+------------------------------+
|
|
| 10.0.5 or later | 20.0.x (but at least 20.0.5) |
|
|
+-------------------+------------------------------+
|
|
|
|
.. note:: While we understand, that you want to migrate as soon as possible,
|
|
we also don't want to put your data at risk. Since we never know
|
|
what ownCloud changes in a future release, we only allow migrations
|
|
from versions that were released before our last maintenance release,
|
|
so we can at least perform some basic migration tests, before you
|
|
migrate your production instance.
|
|
|
|
1. First download the correct version of Nextcloud from our `older releases page <https://nextcloud.com/changelog/>`_,
|
|
|
|
2. Make sure to have do a :doc:`backup<backup>` before migrating.
|
|
|
|
3. Follow the upgrade instructions described in the :doc:`manual_upgrade` manual.
|
|
|
|
4. When migrating to Nextcloud 20.0 or later, you will also need to run the following commands after ``occ upgrade``:
|
|
|
|
* ``occ db:convert-filecache-bigint``
|
|
* ``occ db:add-missing-columns``
|
|
* ``occ db:add-missing-indices``
|
|
* ``occ db:add-missing-primary-keys``
|
|
|
|
5. If system cron was used, please verify if crontab entry was using the command ``occ system:cron``. If yes, please adjust it to use the ``php`` command instead according to :ref:`the background jobs configuration documentation<system-cron-configuration-label>`
|
|
|
|
6. Use the :doc:`Nextcloud built-in updater<update>` to update your instance to the newest version.
|
|
|
|
7. Make sure to also verify the "Security & setup warnings" in the "Overview" section on the settings page.
|
|
|
|
8. In some cases, apps installed from the ownCloud Market might have been disabled as incompatible
|
|
(ex: calendar and contacts), so you should reinstall the Nextcloud ones using
|
|
``occ app:enable calendar``, ``occ app:enable contacts``, etc
