The 3 choices now available for Tribes are:

Aggroed: "If you own a token or tribe on steem-engine and want to stay on steem there's nothing you have to do.

If you own a token or tribe on steem-engine and want to move to hive one option is to continue having your token live on steem-engine, but have payouts work with hive instead of steem for the base token.

If you own a token or tribe on steem-engine and want to move entirely to hive your token name will be reserved, you can get the token and make it stakable and delegatable, airdrop it as you see fit to users, and alter things around with your existing tribe."
