Yes, transition will take some time. To the minute (3:40 p.m. UTC if I calculate right) I can not comment via hive and when I upvote or rehive (reblog) those two actions appear on steem and not hive.

From a steem-engine perspective I found some news at @splinterlands that they will wait and see as well so the usual operations are going to be on steem.
