The FCC announced recently that it has retired the legacy CORES system and is instructing licensees to migrate to a new email-account-based system. The ARRL Letter today discusses this.

Has anyone tried migrating their FRN over to the new FCC CORES system? I didn't have any issues creating the new email/username-based account and associating my FRN. However, I can't seem to do much else. What is the system supposed to do? It looks like most of the functions that I would ever need to use – like renewing a license or changing my address – remain in the FRN-account-based ULS anyway. And that system is still accessible, as of today.
