Migrate DECK to another NextCloud instance

[speedAmaster]

is there any possibility to export DECKs (incl attachments) from one instance and import to another NextCloud instance?

[aleadco]

We are having this need too. We need to migrate to a new NC instance but we didn't want to lose the created projects. It would be a great feature...

An export/import feature would also help greatly to process personal data in a GDPR-compliant way. According to Article 20 Point 1 GDPR, “the data subject shall have the right to receive the personal data concerning him or her, which he or she has provided to a controller, in a structured, commonly used and machine-readable format and have the right to transmit those data to another controller without hindrance from the controller to which the personal data have been provided.”

The functionality to export and import a whole board would be an important first step.

@RainerKlute please don't mix up topics: An export for being GPDR complient is already available via an occ command.

[RainerKlute]

Not sure what you are talking about, @stefan-niedermann. Which occ command would that be? Following your link, I can neither find the word “GDPR” nor “personal” nor “protection”.
Besides, how should that occ command know whether/what data I am processing in some board are personal data?

@RainerKlute try searching for deck 😉 Also linking to the help forum, where this topic has also been answered.

Unfortunately the occ deck:export some.user command throws an exception, whether some.user is a existing user ID or not.

An unhandled exception has been thrown:
TypeError: Argument 1 passed to OC\Group\Manager::getUserIdGroupIds() must be of the type string, null given, called in /data/nextcloud/lib/private/Group/Manager.php on line 310 and defined in /data/nextcloud/lib/private/Group/Manager.php:327

I filed #3828 with more details on how the implementation should be handled since there is now a server API for this with 24. Let's use this one for tracking.
