When migrating users from VMware 5.0 to new VMware 5.5 hosts should the Vnics be updated from e1000 to VMXnet3? Are there any OS considerations? I presume if they remain on e1000 the only impact will be network performance? thanks

When you move the VM, the VM will be moved using the current settings, no vNICs will be changes, now you need to remove the existing NICs and add new NICs, this has consideration including MAC and driver installation, also downtime

Understood but is there a requirement to remove the old e1000 and add the vmxnet nic. Will the old e1000 continue to function.

You should always, and it's highly recommended to use the VMXNET3 interface, which is a fully virtualized hardware.

Make sure you have VMware Tools installed which includes the drivers for the VMXNET3 interface.

But if you don't update the network interface, you may want to update the VMware Tools for the new hosts.
