Yes, you can migrate VM’s between vSphere clusters (even between different versions) as long as below conditions are met: vSphere clusters must be managed by single vCenter server. vSphere clusters must be within single DataCenter object in vCenter server.
What happens when you put ESXi in maintenance mode?
After the host has entered the Maintenance mode,
no VMs can be deployed or powered-on on the host
. Hosts can be also placed in the Standby mode. When a host is placed in this mode, it is powered off. The vSphere DPM (Distributed Power Management) uses the Standby mode to optimize power usage.

What is VPXA service?
The vCenter Server Agent, also referred to as vpxa or the vmware-vpxa service, is what

. Specifically, vpxa is the communication conduit to the hostd, which in turn communicates to the ESX kernel.
Can we migrate VM from one vCenter to another?
vSphere 6.0 or later lets you migrate virtual machines between vCenter Server instances
. Migration of virtual machines across vCenter Server systems is helpful in certain VM provisioning cases.
Can we migrate VM from one datacenter to another?
You can also use cold migration to move virtual machines from one virtual switch to another, and from one data center to another
. You can perform cold migration manually or you can schedule a task. Moving a powered on virtual machine to a new host.
Migration is quite simple.
Right click the VM and select Migrate. Choose the option to migrate both host and datastore
. If the VM is powered on (which it would be as we are doing vMotion instead of a cold migration) you will see the option is grayed out in the older/ C# vSphere client.
What is a DRS cluster?
Distributed Resource scheduler (DRS) is
a type of VMware vSphere cluster that provides load balancing by migrating VMs from a heavily loaded ESXi host to another host that has enough computing resources, all while the VMs are still running
. This approach is used to prevent overloading of ESXi hosts.

What is the difference between live migration and quick migration?
The only difference between ‘Quick Storage Migration’ and ‘Live Migration’ is that
the first one moves virtual machine storage from one location to another location and later one is capable of moving virtual machine along with the storage from one node to another node in the cluster
.
What is Hyper-V storage migration?
In a nutshell, Hyper-V Storage Migration is
the Microsoft’s technology which can help you move the virtual machine’s (VM’s) storage from one location to another without experiencing any compatibility issues
.
Shared nothing live migration is a feature of Microsoft Hyper-V 3.0 and VMware vSphere 5.1 that allows a virtual machine (VM) to be moved from one physical server with direct-attached storage to another physical server with direct-attached storage.

vMotion does not require environments with shared storage
. This is useful for performing cross-cluster migrations, when the target cluster machines might not have access to the source cluster’s storage. Processes that are working on the virtual machine continue to run during the migration with vMotion.
How do I move a VM to another host without vMotion?
You can move VCSA to the other host by
registering the VCSA VM on the second host
. You simply find the VMX configuration file in the datastore browser on the second host, register the VCSA VM temporarily on this host, start it up, and use your vSphere Lifecycle Manager as you usually do.
