Anyone know how to copy accounts from v2?  Is it possible yet?  I'd rather not recreate everything manually!

If you're moving all your clients to a new server you don't have to, just perform a full migration.

However, I'm afraid this won't apply for single accounts.

I apologize, I stuck this in the wrong thread.  I was meaning to put migrate from v2 to v3.

I have moved this topic to v3 General.

And responding to your question, this tool will be released when v3 reaches stable.
