vmware ESXi 5 has expired before i could export my guests

Hi all, I'm currently studying for xenapp 6 exam and and i put the environment on top of  VMWare 5.1 ESXi because i needed to run the access gateway appliance that would only run on ESX.
OK, so i deployed vmware workstation 9 and the deployed 2 ESXi 5.1 servers and installed 3 guests on each of the servers. I have another 2008 server that i deployed vsphere center on which i created the data store and added the 2 ESXi servers. My storage is a SSD drive using starwind to simulate a NAS drive.
 
Ok, here's my problem, One of my ESXi servers has run out of the 60 day license and on top of that i have crashed my vsphere center server image as well.
So, i deployed a new 2008 virtual server, installed vcenter server and then the vcenter client. I was able to add (or transfer) ESX1 host 1 with 3 guests into the new vcenter server but when i try to add ESXi 2 it wont let me instead asking my to update the license. I can use the vsphere client to log onto ESXi2 host and i can see my 3 guests but how do i get my guests off of the host and onto my new host?. I know it was dumb to let the license expire but i have a lot of work on the 3 guests which without them renders the other 3 guests and the whole project as useless. Any help is much appreciated.
