Dear all,

I got it work to migrate in place on VC 2 to 2.5 by

http://communities.vmware.com/thread/75259

Now the new VC 2.5 has been installed and retain my existing datacenter and work with vmotion and ha.

1) What is the next step and upgrade the ESX2 then ESX1 one by one (by VMware-esx-upgrade-from-esx3-3.5.0-64607.zip)?

2) all VM now are running on ESX1. After ESX2 upgraded to ESX 3.5, can I use VC to migrade the ESX1 vm to ESX2 (3.0.2 vs 3.5)?

Thanks! -david
