Problem with migration

ℹ️ Support
1

I’m migrating from owncloud 10.13.2.3 to nextcloud 25, when I install nextcloud and try to launch the page I don’t get any errors, but when I copy (with the appropriate changes) the config.php file from the owncloud installation to nextcloud, I get this error:

Internal Server Error The server encountered an internal error and was unable to complete your request. Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report. More details can be found in the server log.

Could you help me solve it?

Don’t do this, it’s EOL.

I think it’s currently required because of owncloud not supporting php 8.0. From NC 25 you upgrade further, see Migrating from ownCloud — Nextcloud latest Administration Manual latest documentation.

Otherwise, @nemo87, please post the error from the log and add some details, otherwise there’s no way someone can help you.

By deleting and copying the config.php file (modifying it with the nextcloud specifications) I was able to perform the migration, I log in with my user and see my data, I am moving from owncloud to nextcloud precisely because owncloud does not support php 8 (version 25 of NC supports php7, now I will gradually perform the various version upgrades)

Apparently your web server user (probably www-data) cannot write to the directory structures.

Use with caution. E.g. search the internet first.

sudo chown -R www-data:www-data ...

A little tip:

If you only have folders and files in your ownCloud/Nextcloud anyway.

Store data e.g /path/to/owncloud/data/username/files → e.g. move to /backup
Reinstall Nextcloud 31 from scratch
Set up users in new Nextcloud with no files
Copy or move files back to /path/to/nextcloud/data/username/files
read all files in database of Nexcloud:
sudo -u www-data php /path/to/nextcloud/occ files:scan --all

All links, deck, contacts, … are gone.

given commands:

sudo chown -R www-data:www-data /var/www/nextcloud
sudo -u www-data php /var/www/nextcloud/ occ files:scan --all

I keep seeing all the errors listed above…
NB:
my data directory is in a different path than /var/www/nextcloud
i gave the command with the right path:
sudo chown -R www-data:www-data /mnt/cloud/data/
I still get the same error
