To use any Visitor Customization properties on the migrated VM on the vacation spot website, VMware instruments should be put in earlier than the migration to the tenant group is initiated. It may be finished previous to beginning the method whereas the VM is operating on the supply or after it’s transformed on the intermediate website. 


Migrating Legacy and non-vSphere Workloads to VMware Cloud Director - Flow

The steps are as follows:

  1. Put together the vacation spot cloud if it doesn’t have VMware Cloud Director Availability operating.
  2. Deploy and configure the intermediate website.
  3. Deploy vCenter Converter Standalone and its elements accordingly on the supply website.
  4. Convert a VM/bodily machine to the intermediate website. 
  5. Confirm all of the properties (GuestOS kind, model, SCSI controller, and so on.) are accurately populated by means of the vSphere UI. 
  6. (Optionally available) Energy on the VM if wanted.
  7. Configure the migration utilizing VMware Cloud Director Availability. 
  8. (Optionally available) If the VM is powered off, carry out a handbook sync.
  9. (Optionally available) Configure the Restoration settings – Community configuration (Re-IP), Visitor Customization. 
  10. Provoke the migration.

The non-optional steps are marked with their numbers on the diagram.

Vacation spot Website

Because the meant vacation spot for the transformed workloads is VMware Cloud Director, the presumption is that the VMware Cloud Director cloud (together with its group construction) is already in place. If, for some motive, it isn’t, please observe the VMware Cloud Director documentation to set it up correctly.

The primary obligatory requirement is to have all of the VMware Cloud Director Availability home equipment deployed and configured on the VMware Cloud Director cloud.

You possibly can confer with the VMware Cloud Director Availability Reference Architecture and documentation for particular options and directions on learn how to do it.

The cloud website is prepared for migrations when VMware Cloud Director Availability is prepared, and its Service Endpoint handle is accessible.

Intermediate Website

The intermediate website will be deployed and managed by the Cloud Supplier or by the tenants of their information middle. Which choice is extra appropriate have to be decided primarily based on a number of elements comparable to value, obtainable {hardware}, workload criticality, and so on.The location should run vSphere 6.7U3 (already previous Finish of Common Help), 7.0, 7.0U1, 7.0U2, or 7.0U3. There have to be not less than one present consumer with the next permissions required by vCenter Converter Standalone.

One of many following vSphere licenses must be utilized:

  • vSphere Analysis license (if the migration is completed inside 60 days of provisioning the vSphere intermediate website)
  • vSphere Necessities Plus
  • vSphere Customary
  • vSphere Enterprise
  • vSphere Enterprise Plus
  • vSphere Desktop

The vCenter handle have to be accessible from the vCenter Converter Standalone machine.

There are two attainable choices for the deployment of the Intermediate vSphere surroundings:

  • A devoted vSphere per tenant with a VMware Cloud Director Availability On-Premises to Cloud Director Replication equipment paired to the tenant Group within the VMware Cloud Director cloud. It can be a vSphere surroundings operating on the tenant’s infrastructure and managed by them.
Migrating Legacy and non-vSphere Workloads to VMware Cloud Director - Self-service
  • A shared vSphere with a VMware Cloud Director Availability On-Premises to Cloud Director Replication equipment per tenant paired to the tenant Group within the VMware Cloud Director cloud.
Migrating Legacy and non-vSphere Workloads to VMware Cloud Director - Managed service

Choice #1 is appropriate when the Cloud Supplier gives the migration as a self-service or a combined service. Then the tenants can management the entire course of or simply a part of it. For instance, the deployment and operation of the vCenter Converter Standalone. Choices #2 is appropriate when the Cloud Supplier gives a managed service as a result of limiting the visibility of tenants solely to their assets in a shared vSphere surroundings could be difficult.

TipTo optimize the associated fee amassed to the Cloud Supplier by operating the Intermediate website, the transformed VMs can stay powered off and immediately be migrated to the cloud(Chilly Migration). It should require a handbook sync after the migration is configured however will enable even a deployment with much less compute assets for the Intermediate vSphere surroundings. It may well additionally make the most of a slower however cheaper storage answer (NFS, for instance). Nevertheless, these deployment selections must be made solely after contemplating the variety of workloads that might be migrated. Additionally, this strategy would possibly result in a increased downtime interval for the transformed workload.

Deployment steps

These steps have to be adopted to get the intermediate website able to accommodate the transformed VMs.

  1. Deploy and put together the vSphere infrastructure in line with the chosen design (configure networking, storage, and so on.). VMware Cloud Foundation can be utilized for automating the deployment course of. 
  2. Deploy the VMware Cloud Director Availability On-Premises to Cloud Director Replication equipment following the steps offered within the documentation
  3.  Run the preliminary setup wizard of the newly deployed equipment to pair it with the vacation spot cloud. Use the VMware Cloud Director Availability Service Endpoint handle and Group administrator credentials (relying on the design, the credentials must be for a tenant or system Group).
  4. Create a consumer for vCenter Converter Standalone with not less than these permissions.
  5. Carry out all of the community configurations essential to make the vCenter accessible from the tenant website. 

TipThrough the preliminary setup wizard, think about enabling the Permit entry from Cloud setting, which can allow you to configure the migration from the cloud website. 

Supply Website

Due to the assorted sources supported by vCenter Converter Standalone (see Limitations for extra data) and every has totally different necessities, there is no such thing as a advisable structure for the supply website. 

Essentially the most appropriate conversion strategy must be decided by the machine (digital or bodily) proprietor in line with its compliance with the vCenter Converter Standalone necessities and limitations.

For instance, it’s attainable to transform a Hyper-V VM utilizing two strategies:

  • Powered-off digital machine conversion
  • Powered-on machine conversion

A call have to be made primarily based on the Visitor OS distribution, its compatibility with vCenter Converter Standalone, and another elements, comparable to downtime, the necessity to modify the community configuration, and so on.

In case any configuration adjustments to the Visitor OS are required throughout the migration (comparable to community reconfiguration, pc title change, and so on.), then VMware instruments might be obligatory to be put in. Please confer with the Considerations part for extra data on what is required.
