Migrating server/proxy containers between hosts

[juliogonzalez]

Short description

As of today, we document how to run Uyuni on top of openSUSE Leap Micro 5.5

As part of the discussion happening at #9729, we'll change the base OS to openSUSE Tumbleweed or openSUSE MicroOS, so we need a way (tool, documentation...) to migrate the containers/volumes/etc to a new system.

Details

Definition of done:

• We can migrate the server/proxy containers and all related resources (such as volumes, network...) between openSUSE Leap Micro 5.5 and openSUSE MicroOS or Tumbleweed
  • It can be a tool or it can be documentation. What matters is that we have a way of doing it.
• Bonus point: the tool/documentation also works for migrating said resources to non openSUSE OS such as Debian or Ubuntu.
