ERPNext 13 Docker - Ubuntu 22.04 - Jan 2023

I have now 3 sites (e.g. site1.domain.com , site2.domain.com, site3.otherdomain.com) fully running in production environment on Docker Swarm node with Traefik and Portainer installed as per @revant_one manifest ( custom_containers/docker-swarm.md at main · castlecraft/custom_containers · GitHub ) .

VERSION = v13.45.0

I read the thread ( Upgrading to v14 for a Dockerized deployement ) but can’t figure out what’s the safest way to perform an upgrade to v14 . I also want to install HR and Education modules .

Any idea/link of how to do this ?
