Moving large VM to new datastores

$

Read some of the other discussions on this topic .... I have a slight twist... can someone offer guidelines\options on the best way to relocate a very large VM

from a NetApp array to a EMC VNX array.  The VM has 4 disks  -  2 of which are 1+ TB each and currently runs on a ESX 4.0 host.  We want to move the

datastores and guest to a new ESXi 5 host.  Can be 2 steps if necessary.  Taking any downtime will be difficult and must be kept to a minimum.  I've used vMotion

and Converter.  A vMotion test generated a block size complaint.  Converter is very slow and often times out.  If the guest can be powered off I can use the datastore

browser to move the .VMDKs, then unregister\re-register the .vmx.  Slow maybe, but should be better than Converter.  Unfortunately the 4 disks are all separate datastores

and therefore do not reside with the dtatastore containing the .vmx.  Can I still do this by modifying the .vmx to point to the new disk locations ?
