thanks for your reply i am extremly sorry that i didnot give you one important information .

cluster A is managed by one vcenter and cluster B is managed by another vcenter.
i dont know about the same lun but if you could explain me about both possibilites of having same lun and different lun the i will greatfull to you.

how can i migrate the three host along with vms without any down time in this senario.

Are you able to VMotion your VMs between both clusters? In other word, are they seeing the same LUNS? if so then you can complete your restructuring as follow: 1- Evacuate all the VMs on one of your 3 hosts to migrate to the other 2 in that cluster 2- Enter that host into maintenance mode. 3- move the host which is in standby mode to cluster B. 4- get the host out of maintenance mode. 5- Migrate as many VMs from cluster A to B trying to free up a second host in cluster A. 6- then repeat step 2-4 for the second host. 7- repeat the procedure for the last server. I hope this help, Eiad Hi Abyakta,

4- get the host out of maintenance mode.
5- Migrate as many VMs from cluster A to B trying to free up a second host in cluster A.
6- then repeat step 2-4 for the second host.
