Hi,
I have two active network adapters on my esxi 5.5 host. I am planning to migrate to a vDS, but want to be sure I have the right setup:
If I put my vcenter Server VM on the 2nd physical NIC and leave the first NIC as the default vmKernel, would this avoid the potential rollback and be the recommended way?
Just do the following:
1. Create the vDS;
2. Add the host to vDS;
3. Move one of vmnics to the vDS uplink;
4. Migrate the management vmkernel to vDS;
5. Migrate the virtual machines to vDS;
6. Move the last vmnic from the vSS to vDS;
7. Delete the vSS.
Let me know if this helps ..

Thanks for the tips. What I am confused about is whether the vmkernel and vm network for the vcenter server should be on seperate vmnics. Please clarify.
The VMKernel interface is from your vSphere ESXi host, not from the vCenter... the vCenter virtual machine will have a virtual network adapter that bind to a port group that is part of a virtual switch and that uses vmnics to get access to physical network.
The VMkernel interface also bind to a port group, but for isolation, a recommended best practice is place on a different port group and not use the same port group of your virtual machines.
Creation of second VMkernel for each host is verry recommended during migration.
