I have researched this issue and seen no answer for this anywhere... but I still have to solve the problem.
Transferring our VMs from Server 2.0 to ESXi 5.1 is taking an extraordinarily long time. For example: 300GB takes 7 days to transfer. The max transfer rate I get is 5Mb/s...! I have tried ssh+wget, WinSCP and VMWare Converter.
Prior to running VMWare this hardware was running Win2k8 and there were no problems with disk speed or network throughput.
So my question is: will a licence for the ESXi remove the bottleneck?
Furthermore: do people have this problem with vSphere?
Any [constructive] advice would be appreciated.
