I will soon be upgrading my OS (Fedora 20) to the latest one (Fedora 22 or 23). I currently have docker installed through Fedora’s repositories (Docker version 1.5.0, build a8a31ef/1.5.0). I will most likely remove and reinstall Fedora from scratch, and I will install Docker from Docker’s own repository so that I can stay up with the latest version.
I have moved the current docker data folder from /var/lib/docker to a separate partition on the disk. Should I assume that Docker 1.8 will be fully compatible with images/containers created by 1.5? So once I configure the new Docker to use the existing data folder, should I expect everything to work? Is there anything else I may need to do so that I don’t lose any containers?
