Due to some database changes that had to be rather sooner than later, there is no possibility to directly upgrade. You must extract the data before hand and import it again. It is recommended to spin up a second instance of authentik to do this.
After that, create a new authentik instance in a different namespace (kubernetes) or in a different folder (docker-compose). Once this instance is running, you can use the following commands to restore the data. On docker-compose, you still have to run the `migrate` command, to create all database structures.
