![]() Selecting your Azure resourceĪfter installing and opening Azure Resource Explorer you will be asked which Azure resource you are connecting to. This article will walk through how to migrate an Azure virtual machine from one tenant to another. Luckily, Microsoft offers a free tool called Azure Storage Explorer which offers the ability to log into multiple Azure tenants to monitor and manage resources within your environment(s). At first glance, this task can appear to be daunting. VSphere 6.0 or later lets you migrate virtual machines between vCenter Server instances.System administrators are often tasked with migrating existing virtual machines from one of their tenants to another. ![]() Migration Between vCenter Server Systems.Unlike Storage vMotion, which requires a single host to have access to both the source and destination datastore, you can migrate virtual machines across storage accessibility boundaries. You can use vMotion to migrate virtual machines to a different compute resource and storage simultaneously. Migration with vMotion in Environments Without Shared Storage.To migrate virtual machines with vMotion, the virtual machine must meet certain network, disk, CPU, USB, and other device requirements. Virtual Machine Conditions and Limitations for vMotion.For virtual machines that are not encrypted, you can select one of the encrypted vSphere vMotion options. VSphere vMotion always uses encryption when migrating encrypted virtual machines. If errors occur during migration, the virtual machine reverts to its original state and location.īefore using vMotion, you must configure your hosts correctly. The virtual machine resumes its activities on the new host.The virtual machine state information (memory, registers, and network connections) is copied to the target host.When the migration with vMotion is requested, vCenter Server verifies that the existing virtual machine is in a stable state with its current host.Migration with vMotion occurs in three stages: This information includes BIOS, devices, CPU, MAC addresses for the Ethernet cards, chipset states, registers, and so forth. The defining and identification information stored in the state includes all the data that maps to the virtual machine hardware elements. The memory content includes transaction data and the bits of the operating system and applications that are in the memory. The state information includes the current memory content and all the information that defines and identifies the virtual machine. When you choose to change both the compute resource and the storage, you can use vMotion to migrate virtual machines across vCenter Server instances, data centers, and subnets. Migrations with vMotion are transparent to the running virtual machine. vMotion migration to another host and datastore is possible in vSphere environments without shared storage.Īfter the virtual machine state is migrated to the alternate host, the virtual machine runs on the new host. When you choose to change both the host and the datastore, the virtual machine state is moved to a new host and the virtual disk is moved to another datastore. The associated virtual disk remains in the same location on storage that must be shared between the two hosts. ![]() When you migrate virtual machines with vMotion and choose to change only the host, the entire state of the virtual machine is moved to the new host. You also can change both the compute resource and the storage of the virtual machine. ![]() With vMotion, you can change the compute resource on which a virtual machine is running. When you migrate a virtual machine with vMotion, the new host for the virtual machine must meet compatibility requirements so that the migration can proceed. Migration with vSphere vMotion allows virtual machine processes to continue working throughout a migration. If you must take a host offline for maintenance, you can move the virtual machine to another host. ![]()
