re-bootstrap existing container from (new) template


Well-Known Member

I have several containers running on debian buster wich I want to upgrade to debian bookworm. As I have strictly separated user data and the rootfs on two disks it would be easy to just install a "fresh" debian 12 on a new root disk and swap them after installation or even just replace the existing root disk with a new unpacked container image.

The only option I found is to delete the container while keeping the disks and recreate it "from scratch" but this would be a "monkey job" in copy & pasting all the configuration settings.

Is there any other option to trigger the bootstrap process on an existing container configuration?

best regards
