Upgrade 10.2.1 to 10.7.0 with Phoenix

Hi,
I’m running ownCloud 10.2.1 dockerized connected to a dockerized cluster of MySQL 5.7.
I would like to upgrade to 10.7.0 but I have a few questions.

1- Do I need to go thru each release or it’s safe to upgrade directly the docker image to 10.7.0.
2- As for Phoenix, I assume I only need to spin the docker image (owncloud/web) and then do the configuration in Oc.

R,
