if i copy back the 0.4.3 version of convoy and convoy-pdata_tools, the volume is there please anyone can help? But if I use the 0.4.3 version, docker 1.11.2 could not read the volume with following error: "Error response from daemon: get jenkins_home: VolumeDriver.Get: Handler not found: POST /VolumeDriver.Get Error: failed to start containers: 86ab "

it turns out in version 0.4.3, the config root is at /var/lib/convoy, but 0.5.0 is using /var/lib/rancher/convoy

Unfortunately when start 0.5.0 daemon with --root /var/lib/convoy, i could see all my volumes and snapshot, but all volumes are missing their names, :(.

Hi @binliuk

We've changed the configuration format for 0.5.0, so it's not compatible with 0.4.3. The version release note warned about it...

Currently we don't support upgrade from 0.4.3 to 0.5.0, so you may want to use backup in 0.4.3 and restore in 0.5.0 to get things right.

Or it's also possible to modify the volume configuration per driver to include the information from old version, but that will require some efforts or tools to sort it out.
