I imported the account 'ashkir' from 'support' to the board 'wi' to the account 'ashkir'.

It imported a old copy of my profile, when it had a old sig, old avatars, no im information, and different display name.

Is this a result of the server move and old cache, or something that is being worked on?

It's the result of 'support' and 'wi' being on two completly different systems. When everything is on the latest version that issue won't exist.
