Hello experts,

I am trying to migrate a vmware server from one host to another in vCenter. I keep getting this error at the select destination
 Unable to access the virtual machine configurationj:unable to access file [datastore2]REMOTE/REMOTE.vmdk
Virtual Disk 'Hard Disk 1' is not accessible on the host: Unable to access file [datastore2] REMOTE/REMOTE.vmdk
Network interface Network Adapter 1' uses network 'VM Network', which is not accessible

Are there any settings that need to be changed?

Yes. Check yours NIC settings.  One is set for the VM Network which the other host cannot see.

where is the server located? is it on local storage or shared storage.
for me it looks like the machine you are trying to migrate is located on local storage datastore. Then migration
will not happen. If it is on shared datastore please check of the datastore is visible from destination.

or you can try power down the server and do a cold migration

Even with a cold migration, I get the same error message. I also tried clone to new virtual machine and I am getting "Network interface 'Network Adapter 1' uses network 'VM Network', which is not accessible

On your destination ESX Server you will need to have a port group labeled as "VM Network"

That is created by default when ESX(i) is installed. I assume you are using vMotion in vCenter to perform the migration. When hosts are configured in vCenter, it is best to be consistent in things like names for Port Groups - what you will need is a port group that has the same name on each server, then in the virtual machines network settings you can associate the Network Adapter with that commonly named network.

Alternatively you can use VMware converter, either the stand alone version or the vCemter Converter Enterprise that you can install as part of the vCenter product.

Good Luck

Do you have vMotion? if so it might be simpler to clone it where it is, then vmotion the clone!

Do you have any shared storage? Or is it local storage on both servers?
