It is possible to make changes early, before start of the release candidate suite as indicated with vertical arrows on the diagram. e.g. from enfo:cf:00/12 to oper:fc:00/12. Making early changes would give more time for adjustment of programs using disseminated data. However, we do not recommend changing dissemination requirements containing 06/18 runs. This is because current equivalent deterministic streams scda and scwv are going to be discontinued and integrated to oper and wave in 50R1. Therefore, it will be easier to adjust these during the release candidate phase.
