[atlas] upgrading 5080 swprobe to 5100 on Debian loses config?

Hi - I tried upgrading a software probe that runs on Debian from version 5080 to the 5100 binaries provided by the project, and while the old atlasswprobe package is being removed, it seems there is no attempt to migrate the existing probe key or other configuration? What's the recommended path here, back up the key and copy it into the new configuration directory, or just start a new probe from scratch? Alex.
