Hi, lucky I saw this as is on a MAPX post.
All STEEM and SP and delegations will be copied over to Hive automatically, so no need to do anything.
Indeed, being so near to launch, I wouldn't change any delegations just now.
Yes, MAPR will continue on Hive, but will take a few days to calculate the value of the tokens held within Steem-Engine.
Will post on Hive account@accelerator within the next hour.
Thanks for your support!
