This document specifies the process that Certification Authorities
(CAs) and Relying Parties (RPs) participating in the Resource Public
Key Infrastructure (RPKI) will need to follow to transition to a new
(and probably cryptographically stronger) algorithm set. The process
is expected to be completed over a timescale of several years.
Consequently, no emergency transition is specified. The transition
procedure defined in this document supports only a top-down migration
(parent migrates before children).
