Rocky 9.x Owncloud Manually moving DataDirectory

We can change path of owncloud DataDirectory as follows: (Assuming moving from /var/www/owncloud to /mnt/owncloud )

Enable maintenance mode. For example

cd /var/www/html/owncloud
sudo -u apache php -f occ maintenance:mode --on

sudo -u apache php -f occ maintenance:mode

Optionally stop web server (Dont stop MariaDB database)
```
systemctl stop httpd
```
Figure out various datadirectory in use. Although config/config.php mentions about only one DataDirectory the oc_accounts table might have home value which is not a sub-folder of config/config.php DataDirectory. In such cases we need to either copy/migrate all these other home folders also. To see various home folders in use, use below SQL query
```
select * from oc_accounts;
```
Look at value of home column. Validate that they are sub-folders of same parent DataDirectory and plan accordingly.

We can move the home folders to a common location. But after that we must update various user home path appropriately.
Move the files to new folder, Remount old Data directory on new path. If instead of move copy is preferred then use:
```
#Use below only if you want to copy instead of moving, Use twice space
rsync -a /var/www/owncloud/ /mnt/owncloud/
```
Trailing / in both paths is critical
Connect to MariaDB using 'mysql'. DB name, Username and Password are part of config/config.php file. For example
```
mysql -u <username> -p

#On mysql> prompt
use <db-name>
```

Update oc_storage MariaDB table using:

UPDATE oc_storages SET id='local::/mnt/owncloud/data/' WHERE id='local::/var/www/owncloud/data/';

Trailing / in both paths is critical

Update oc_accounts table using:
```
UPDATE oc_accounts SET home = REPLACE(home, '/var/www/owncloud/data/', '/mnt/owncloud/data/' );
```
Trailing / in both paths is critical

If various accounts have different home folder (Not common DataDirectory, update this step appropriately)
Validate that output of below SQL is empty:
```
SELECT * FROM oc_jobs  WHERE class = 'OC\Log\Rotate';
```
If it is not empty use reference link below to understand how to update path in oc_jobs table
Look at application setting to see if any application has cached path as part of its settings:
```
cd /var/www/html/owncloud
sudo -u apache php -f occ config:list
```
If application has cached path then use reference link below to understand how to update path in oc_jobs table
In config/config.php file update DataDirectory path
Note that value of DataDirectory does not ends with trailing /
Start http service, if it was stopped
```
systemctl start httpd
```

Remove owncloud from maintenance mode. For example

cd /var/www/html/owncloud
sudo -u apache php -f occ maintenance:mode --off

sudo -u apache php -f occ maintenance:mode
