ReadPeersJSON consumes a legacy peers . json file in the format of the old JSON peer store and creates a new - style configuration structure . This can be used to migrate this data or perform manual recovery when running protocol versions that can interoperate with older unversioned Raft servers . This should not be used once server IDs are in use because the old peers . json file didn t have support for these nor non - voter suffrage types .
