[SOLVED] Migrating from owncloud 8.2.1.4 to nextcloud 9.0.58

#1

Sorry, i know i am a little late for migration to nextcloud - especially from such an old owncloud instance.
Please be keen.

I tried to follow this post:

My system:
Debian 7
Mysql 5.5.40
Apache 2.22
Owncloud 8.2.1.4
(all installed via apt-get install owncloud)
(my config points to data dir: /vagrant/data/owncloud)

What i did:
cd /var/www
;#most up-to-date version in point of writing
wget https://download.nextcloud.com/server/releases/nextcloud-9.0.58.tar.bz2
tar xvjf nextcloud-9.0.58.tar.bz2
cp -R owncloud/config nextcloud/config
cp -R owncloud/data nextcloud/data
chown -R www-data /var/www/nextcloud
cd /var/www/nextcloud
su www-data
php occ maintenance:install

But this installs nextcloud using a sqlite database - empty, no users, no files. All data is missing.
There was no “update” command available in command line tool occ.

It is not absolute clear to me, if i need to update owncloud 8.2.14 to owncloud 8.2.11 (released on Apr 18 2017; most up-to-date version in point of writing) prior to migrating to nextcloud.

Or did i miss another thing?

Yes, normally you should update to the latest 8.2.x release first. If you change the path of your data folder, you should have a look into your config/config.php and check the paths. The database should fix the paths to the data-folder but that has been implemented recently. I would first upgrade keeping the original locations (at least for the data folder). If then everything works, I would touch the data folder (and I would also use a rather recent version, NC 11, or in a few weeks NC 12).

For NC 9, you need at least php 5.6, Debian 7 has an older version by default.

I upgraded owncloud vom 8.2.1.4 to 8.2.11 using the debian package manager.

This page:
https://docs.nextcloud.com/server/9/admin_manual/installation/system_requirements.html
states that PHP 5.4 is enought.

I will stop here for today and resume to update within the next few days.

I migrated to nextcloud 9.0.58 with success!

Steps:
cd /var/www
;#most up-to-date version in point of writing
wget https://download.nextcloud.com/server/releases/nextcloud-9.0.58.tar.bz2
tar xvjf nextcloud-9.0.58.tar.bz2
rm -Rf nextcloud/config
rm -Rf nextcloud/data
cp -R owncloud/config nextcloud/config
cp -R owncloud/data nextcloud/data
chown -R www-data /var/www/nextcloud
cd /var/www/nextcloud
su www-data
php occ upgrade
php occ app:enable calendar
php occ app:enable contacts

no need to change the data-folder location because it stays the same /vagrant/data/owncloud.
Maybe i rename the mount point in a later step.

BTW: “occ” of nextcloud should be renamed to “ncc” by the nextcloud developers.
