Quick Migration between two esxi 4.1 paid hosts

[voktv]

Hi all,

My Support Case ID is #02053104.

Infrastructure I have is:

Two esxi 4.1 hosts licensed with vSphere 4 Essentials, one esxi 5.5 free licence and one esxi 6 also free licence. All four hosts are standalone. There is no shared storage - SAN.
I have licence for vCenter 4 Essentials, but vCenter is not implemented.

Veeam B&R is installed on Windows 10 VM on esxi 5.5 free host.

I tried many times Quick Migration of diffrent Windows VMs between those two esxi 4.1 hosts.
Processes failed with:
Copying VM state Error: NFC server [ip of destination esxi 4.1 host] is busy.
Unable to receive file.
Exception from server: Shared memory connection was closed.

Only one time the process of quick migration was successful.

Dns system doesn't work well but I'm accessing esxi hosts via IP addresses.

I have two questions:
1. What could be the reason for this problem?
2. I want to move VM from one esxi 4.1 host to another one with the minimum downtime, don't have SAN, is Quick Migration the best solution?

Many thanks.

Hi voktv, welcome to the community!

1. Support team should provide detailed information on the issue.

2. I want to move VM from one esxi 4.1 host to another one with the minimum downtime, don't have SAN, is Quick Migration the best solution?

As the second option to Quick Migration I’d recommend you to use Replication job followed by planned failover.This should be the best solution with minimum downtime.

Thanks!
