What are prerequsite to perform vMotion across vCenter ?
1. Both vCenter should be in Linked mode ?
2. Both vCenter should be part of same SSO ?
3. vMotion will flow over vMotion network ? vMotion network need to be comman between both vCenter ?
4. VMs network should be available both vCenter
How to perform it (I think possible only through web client) ?

I want to make sure that Link mode means you can manage the Multiple datacenter but the operation you can not perform across the datacenter.
4th Point you are talking about network is same across both but that network is routable. If yes than you can communicate but not vMotion acrosss the datacenter.
