Perform this task to migrate a VMware VM to UIS. The migration does not require any agents and features short service interruption time.
Make sure the VMware VM does not use any independent-persistent or independent-nonpersistent disks.
To migrate the VMware VM while it is online, make sure it is installed with VMware tools.
Make sure the host to which the VMware VM belongs uses ESX/ESXi 4.0 or higher.
Make sure the hardware version of the VMware VM is 7 or higher.
Make sure the VMware vCenter version is vCenter6.0, vCenter6.5, vCenter6.7, or vCenter7.0.
Make sure the vCenter is accessible on port 443, and the ESXi host is accessible on port 902.
Make sure the VMware VM does not use an SR-IOV passthrough NIC.
A VM in VMware vCenter 6.0 cannot be migrated to UIS if the VM uses NFS. To migrate such a VM to UIS, you must first change its storage to VMFS on VMware.
If VMware VMs use IPv6 addresses, you must enable VM IPv6 address management in system parameters before migrating the VMware VMs to CAS. If you do not enable VM IPv6 address management, the VMs do not have IPv6 addresses after they are migrated.
A VMware VM cannot be migrated to UIS if it uses an RDM disk in physical compatibility mode. A VMware VM can be migrated to UIS if it uses NFS or uses an RDM disk in virtual compatibility mode. A VMware VM that uses a VMFS disk can be migrated to UIS, regardless of whether the storage resources are provided by SAN, iSCSI, or a local disk.
A VM in VMware vCenter 6.0 cannot be migrated to UIS if the VM has snapshots. To resolve this issue, contact the technical support.
A VMware VM cannot be migrated to an ARM host.
To avoid migration failure, make sure the destination storage pool has sufficient space.
You must configure a network IP address for a VMware VM after the VM is migrated to UIS.
When a VMware VM is in sleep mode, its VMware tools stops running and the VM cannot be shut down automatically, which might cause migration failure or data loss. Therefore, do not set a VMware VM to auto sleep or energy saving mode during the migration.
To avoid migration failure, do not operate a VM on VMware while the VM is being migrated to UIS.
By default, a VMware VM that uses the Windows server 2003 or Windows XP operating system uses the IDE disk bus type after it is migrated to CAS. After the migration, you must manually install CAStools.
To migrate a VMware VM that uses the Windows server 2003 or Windows XP operating system, make sure the number of disks on the VM does not exceed four (including floppy drives and optical drives).
After a VMware VM that uses the Windows Server 2008 operating system is started (automatically or manually) for the first time after it is migrated to UIS, you must restart the VM to have the drivers run correctly.
If a VMware VM cannot be quiesced during the migration, UIS will prompt snapshot deletion failure and VMware will prompt snapshot saving and VM quiescence failures. In this scenario, quiesce the VM as instructed in the official website of VMware, and then continue the migration.
By default, a VMware VM uses the thin provisioning mode after it is migrated to UIS.
A VMware VM cannot be migrated to an RBD storage pool.
On the top navigation bar, click VMs.
From the left navigation pane, select External VMs > vCenter Site Name > Cluster Name.
Click the alias of an external VM to be migrated.
Click Migrate.
Configure the parameters as described in "Parameters."
Click Finish.
Basic Info
Alias: Specify an alias for the VM.
VM Startup/Shutdown: Select an action to take for the VM.
Forcibly Shutdown—Enable this feature for the system to forcibly shut down the VM during migration.
Start After Migration—Enable this feature to start the VM automatically after it is migrated.
Host
Host: Select the target host to which the VMware VM will be migrated.
Storage
Target Disk Size: Set the disk size for the target VM. It cannot be smaller than the disk size of the source VM.
Target Storage File: Specify the target storage file name.
Target Storage Pool: Select a storage pool for the target VM.
Network
Source MAC: Set the MAC address of the target VM. It is the MAC address of the source VM by default.
vSwitch: Select a vSwitch for the target VM.
Port Profile/Port Group: Select a port profile/port group for the target VM.
