Cold Migrations across difference VCSA's - network requirements

[virtualizingtheworld]

Hi,

Have a few VM's that I want to migrate (cold migration) between 2x different VCSA 7.0 Update 2

This should use the vmk which has Provisioning enabled or otherwise by default will use the Management vmk

Feature is explained here but what are the ports that need to be opened between the ESXi's for this to work? (they are in different networks)

Ciao 

The TCP port required for Across vCenter Migration are:

• 8000 and 902 for vMotion and NFC between ESXi
• 443 between both vCenter Servers
• 443 between vCenter Server and the ESXi server (this is a requirement to have the ESXi host added to vCenter Servers)

Cross vCenter Migration and Clone requirements in VMware vSphere 6.x and later (2106952)

and if you check  the function of a single TCP port is indicated in this KB

Port requirements for ESXi (2039095) (vmware.com)

ok so cold migration still uses TCP/8000 as this is what I could not see in documentation?

Ciao   

There are various references to the 8000 tcp port
The original product documentation in the requirements:

https://flings.vmware.com/cross-vcenter-workload-migration-utility#requirements

reports using the KB requirements
https://kb.vmware.com/s/article/2106952

where it is indicated

 

also on this site it is indicated

Yes confirm that cold migration worked withTCP/8000 and TCP/902 between the Source/Destination Hosts
