Hi Guys,
We have vCentre 4 which manages hosts for VI 3.5 and also vSphere 4 hosts as part of migration to vSphere 4. Due to hardware differences, I had to perform cold migration on vm's from VI 3.5 to vSphere 4 host's. The migration process completed successfully on all the vm's but on some vm's when I power them on, i have lost the ablity to communication with, eg I can not ping the vm's any longer???
if I re migrate the trouble vm's back to VI 3.5 and it works straight away, not sure why?
Any help is much appreciated to resolve this issue,
regards,
