Vsphere Essentials 5.1 - I need to decommission one of my ESXi servers.  All storage is local.  What is is the best/fastest way to get the data moved from one server to another.  

Currently I am trying to "Export to OVF" from my laptop while connected to vCenter, but it estimates that export a 100GB VM will take 16 hours.

Is this the best method - Export to OVF and the Import the OVF on the new server?  Is there a faster was to do the export/import?

Thanks for your help!

is the usage of the converter an option? then you can directly migrate the vm from one ESXi to another ..

Additional Info with regards to the 16 hour export estimate.- Provisioned storage on the VM is 850GB.  Used storage is 100GB.  Export is running so I can't see if it is thick or thin provisioned (Edit Settings is Grayed out).

You use the option to convert the machine (process is called like that) and then you choose existing virtual infrastructure and then you enter current ESXi host credential choose machine to migrate and then enter new ESXi credentials adjust VM settings and then the process starts.

THe copying is done directly from one ESXi host to another no need fro intermediate machine.

Is the VM 100GB in size, or have a 100GB  of data, because Exporting does NOT export 100GB! It just exports the data!

(EDIT just seen this!).

100GB is 100GB, it will take time, using any method....based on network speed, source datastore speed, and target speed.....

There is NO real fast way, but Exporting to a Laptop is going to be slow, unless you laptop is superfast!

have a look at this method ?

What network you have? Can it be better? i.e can you drop cross-over cable between open gigabit ports?
You must shut down VM, then use veeam scp to make direct host to host transfer without messing with workstation disk, then start vm in new location and delete in old.

Rotational disks do ~50MB/s which means 3GB/min or 100GB in half hour.
