Move a VM from one Vsphere to another

I want to move a vm from one vsphere server to another because I'm out of disk space on the old server.  I'm not sure how to do that.  Server hosting client I want to move is an ESXi 5.5 standard.  Machine to migrate to is ESXi 6.0'

 

What tool, command, etc. do I use?

Any datastores common to both hosts? Are the hosts managed by a vCenter Server or not?

No shared data stores.  Both servers are available in a vcenter server.

>>> Both servers are available in a vcenter server.

If you are using at least ESXi 5.5 Update 2, and have a vSphere  Essentials Plus license, you can live migrate VMs between hosts without shared storage (assuming compatible CPUs, and a vMotion network configured).

Other than this, the migration wizard should allow you to migrate powered off VMs.

Where can I find a step by step guide to migrate a powered off VM?

You can use cold migration to move a virtual machine and its associated disks from one datastore to another. The virtual machines are not required to be on shared storage.

Prerequisites

  • Make sure that you are familiar with the requirements for cold migration. See Cold Migration.

  • Required privilege: Resource.Migrate powered off virtual machine

Procedure

  1. Power off or suspend the virtual machine.
  2. Right-click the virtual machine and select Migrate.
    1. To locate a virtual machine, select a data center, folder, cluster, resource pool, host, or vApp.
    2. Click the Virtual Machines tab.
  3. Select the migration type and click Next.
    Option DescriptionChange compute resource onlyChange storage onlyChange both compute resource and storage
    Move the virtual machine to another host.
    Move the virtual machine’s configuration file and virtual disks.
    Move the virtual machine to another host and move its configuration file and virtual disks.
  4. If you change the compute resource of the virtual machine, select the destination compute resource for this virtual machine migration and click Next.

    Any compatibility problem appears in the Compatibility panel. Fix the problem, or select another host or cluster.

    Possible targets include hosts and DRS clusters with any level of automation. If a cluster has no DRS enabled, select a specific host in the cluster rather than selecting the cluster.

    Important:

    If the virtual machine that you migrate has an NVDIMM device and uses PMem storage, the destination host or cluster must have available PMem resources. Otherwise, the compatibility check fails and you cannot proceed further with the migration.

    If the virtual machine that you migrate does not have an NVDIMM device but it uses PMem storage, you must select a host or cluster with available PMem resources, so that all PMem hard disks remain stored on a PMem datastore. Otherwise, all the hard disks use the storage policy and datastore selected for the configuration files of the virtual machine.

    Important:Migrating a virtual machine that has an NVDIMM device or a vPMem disk to a host that does not have the proper license fails and leaves the virtual machine in an unmanageable state for 90 seconds. You can afterwards retry the migration and select a destination host that is licensed to use PMem devices.
  5. If you change the storage of the virtual machine, enter the required details in the Select Storage page.
    1. Select the storage type for the virtual machine configuration files and all the hard disks.
      • If you select the Standard mode, all virtual disks are stored on a standard datastore.
      • If you select the PMem mode, all virtual disks are stored on the host-local PMem datastore. Configuration files cannot be stored on a PMem datastore and you must additionally select a regular datastore for the configuration files of the virtual machine.
      • If you select the Hybrid mode, all PMem virtual disks remain stored on a PMem datastore. Non-PMem disks are affected by your choice of a VM storage policy and datastore or datastore cluster.
      Selecting the type of storage is possible only if PMem or Hybrid storage types are available in the data center.
    2. Select the format for the virtual machine disks.
      Option ActionSame format as sourceThick Provision Lazy ZeroedThick Provision Eager ZeroedThin Provision
      Use the same format as the source virtual machine.
      Create a virtual disk in a default thick format. Space required for the virtual disk is allocated during creation. Any data remaining on the physical device is not erased during creation. Instead, it is zeroed out on demand on first write from the virtual machine.
      Create a thick disk that supports clustering features such as Fault Tolerance. Space required for the virtual disk is allocated at creation time. In contrast to the thick provision lazy zeroed format, the data remaining on the physical device is zeroed out during creation. It might take longer to create disks in this format than to create other types of disks.
      Use the thin provisioned format. At first, a thin provisioned disk uses only as much datastore space as the disk initially needs. If the thin disk needs more space later, it can expand to the maximum capacity allocated to it.
    3. Select a virtual machine storage policy from the VM Storage Policy drop-down menu.
      Storage policies specify storage requirements for applications that run on the virtual machine. You can also select the default policy for vSAN or Virtual Volumes datastores.
      Important:If the virtual machine hard disks use different storage policies, the new policy that you select only applies to non-PMem hard disks. PMem hard disks are migrated to the host-local PMem datastore of the destination host.
    4. Select the datastore location where you want to store the virtual machine files.
      Option ActionStore all virtual machine files in the same location on a datastore.Store all virtual machine files in the same Storage DRS cluster.Store virtual machine configuration files and disks in separate locations.
      Select a datastore from the list and click Next.
      1. Select a Storage DRS cluster.
      2. (Optional) To disable Storage DRS with this virtual machine, select Disable Storage DRS for this virtual machine and select a datastore within the Storage DRS cluster.
      3. Click Next.
      1. Click Configure per disk.
        Note:You can use the Configure per disk option to downgrade from or upgrade to PMem storage.
      2. For the virtual machine configuration file and for each virtual disk, select Browse, and select a datastore or Storage DRS cluster.
        Note:Configuration files cannot be stored on a PMem datastore.
      3. (Optional) If you selected a Storage DRS cluster and do not want to use Storage DRS with this virtual machine, select Disable Storage DRS for this virtual machine and select a datastore within the Storage DRS cluster.
      4. Click Next.
  6. If you change the compute resource of the virtual machine, select destination networks for the virtual machine migration.

    You can migrate a virtual machine network to another distributed switch in the same or to another data center or vCenter Server.

    Option ActionSelect a destination network for all VM network adapters connected to a valid source network.Select a new destination network for each VM network adapter connected to a valid source network.
    1. Click the arrow in the Destination Network column and select Browse.
    2. Select a destination network and click OK.
    3. Click Next.
    1. Click Advanced.
    2. Click the arrow in the Destination Network column and select Browse.
    3. Select a destination network and click OK.
    4. Click Next.
  7. On the Ready to complete page, review the details and click Finish.

Results

vCenter Server moves the virtual machine to the new host or storage location.

Event messages appear in the Events tab. The data displayed on the Summary tab shows the status and state throughout the migration. If errors occur during migration, the virtual machines revert to their original states and locations.

1.  I don't get an option to "Migrate" when I right-click on the powered off machine.

The Migrate option is only available from the vCenter Server interface, i.e. not while logged in to the ESXi host's GUI  directly.
