I am looking to move several tasks from one list to another. Is there a way to do this that does not involve moving each task individually?
Or is there a way to export a list , and re-import it into a different one?
Right now there’s no way to do this in Bulk.
You could export your Vikunja data, edit the json and then import the edited file.
In addition, you can try it on the command line with vja:
vja edit TASK_IDS --list-id
like for example
vja edit 11 12 13 --list-id=2
see
vja edit --help
