The docs say to migrate as a gateway. I don't see anything else about this. Anyone have any further information?
you have a reference? It doesn't make to much sense.. but I may have been in dilirium when I wrote parts of the docs :-/

A gateway allows for 1:1 exchanges ... e.g. bitUSD<->USD
since BitShares 2.0 is its own exchange, there is no need for any centralized exchange to offer a paid bitUSD : BTS or bitUSD : bitBTC
and... I am aware of what a gateway is... no offence but that last comment was less than helpful
