It’s also recommended that if you upgrade from 6.0 to 6.5, or 6.5 to 6.7, that you upgrade the other side of the environment to that same version as well. All of your environments must be upgraded to at least 6.0. Prior to 6.0, you had to shut VMs down and export/re-import manually. The source and destination vCenter and ESXi hosts must be running at least vSphere 6.0 or later. Let’s outline a few tips for a successful cross vCenter migration.
Secure (recommended if not using vSphere 6.5 or later encrypted vSphere vMotion).Same virtual machine IP address available at the destination.There are some requirements for long-distance vMotion as well that we need to address first. You might consider these types of migrations for things like disaster recovery, VMware Site Recovery Manager, Multisite load balancing or follow the sun scenario support. The days of being locked into one vCenter are long gone. All of the old boundaries we used to have are no longer an issue. Now, we also have to keep in mind that the hosts must meet the same CPU compatibility standards. You can change compute, network, storage, and management all in one concurrent move. Cross vCenter migrations were introduced in vSphere 6.0 and they allow virtual machines to be moved from one vCenter Server instance to another. We’ve got a few posts on vMotion already but none on cross vCenter migrations. After vCenter Server is assigned to a new license key, all disconnected hosts reconnect to the vCenter Server system.For this post, I wanted to put together a few tips on cross vCenter migrations. Until the vCenter Server system is assigned a new license, you can manage the virtual machines on the disconnected hosts by logging into each host separately. The virtual machines running on the disconnected hosts remain intact. When the license or evaluation period of a vCenter Server system expires, all hosts disconnect from that vCenter Server system. The evaluation mode license of vCenter Server expires after the remaining 40 days of the evaluation period. You can set vCenter Server back to evaluation mode only within 60 days after its installation.įor example, suppose that you install a vCenter Server system and use it in evaluation mode for 20 days and assign the system an appropriate license. An evaluation mode license of a vCenter Server system expires 60 days after the product is installed no matter whether you assign a license to vCenter Server or not. When you install a vCenter Server system, it is in evaluation mode. To license a vCenter Server system, you need a vCenter Server license that has the capacity for at least one instance. VCenter Server systems are licensed with vCenter Server licenses that have per-instance capacity.
