During the standard upgrade of 6.7 vSphere to 7.0. Step 1 requires the deployment of a new vSphere instance. All goes through well until the start of the deployment, never reaching past 0% erroring out with the following message: Failed to send file [disk-0.vmdk] to the host [plumbus.cloud], please check the network connection. I have attached the log for reference. Has anyone else come across this issue?
Are you using vSAN datastore ? To avoid such network issue, can you try to place the source 6.7 and destination 7.0 on the same ESXi host and then retry the VC upgrade.
