V2Migration updates the repo so that nodeID is no longer part of the execution and job store paths. It does the following: - Generates and persists the nodeID in the config if it is missing, which is the case for v2 repos - Adds the execution and job store paths to the config if they are missing, which is the case for v3 repos - Renames the execution and job store directories to the new name if they exist
