You could tried to pif-forget and pif-introduce the network interface as 
per the following doc : http://support.citrix.com/article/CTX121615
However the easiest thing to do when moving a server from one pool to 
another, I think, is to get the host out of the pool, re-install it and 
join it to the new pool. It should take 5-10 minutes. If the servers is 
on the other side of the island and you don't have advanced ipmi/ilo 
card for re-install, then it is another story.
Cheers,

Denis
