The idea is to unify all SONiC CLI subcommands to use hyphens as separators instead of underscores to align more with the Linux standard. This will require a period of transition where we support both formats to allow users to migrate to using the hypenated versions, so we will need to temporarily create aliases for all affected commands so that both the hyphenated and underscore version work. Then we can set a date to deprecate the versions with underscores.
