Yow will discover extra concerning the supported Working Techniques here.

For any conversion limitations, please verify here.

Concerns

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

Circulation

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 many others.) are accurately populated via the vSphere UI. 
  6. (Non-compulsory) Energy on the VM if wanted.
  7. Configure the migration utilizing VMware Cloud Director Availability. 
  8. (Non-compulsory) If the VM is powered off, carry out a guide sync.
  9. (Non-compulsory) 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 Web site

For the reason that 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 cause, it’s not, please observe the VMware Cloud Director documentation to set it up correctly.

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

You’ll be able to seek advice from the VMware Cloud Director Availability Reference Architecture and documentation for particular options and directions on find out how to do it.

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

Intermediate Web site

The intermediate website might be deployed and managed by the Cloud Supplier or by the tenants of their knowledge heart. Which possibility is extra appropriate have to be decided based mostly on a number of components resembling value, accessible {hardware}, workload criticality, and many others.The positioning should run vSphere 6.7U3 (already previous Finish of Normal Help), 7.0, 7.0U1, 7.0U2, or 7.0U3. There have to be a minimum of one current 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 achieved inside 60 days of provisioning the vSphere intermediate website)
  • vSphere Necessities Plus
  • vSphere Normal
  • vSphere Enterprise
  • vSphere Enterprise Plus
  • vSphere Desktop

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

There are two doable choices for the deployment of the Intermediate vSphere setting:

  • 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 may also be a vSphere setting 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 presents 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 presents a managed service as a result of limiting the visibility of tenants solely to their assets in a shared vSphere setting is likely to be difficult.

TipTo optimize the price collected 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’s going to require a guide sync after the migration is configured however will enable even a deployment with much less compute assets for the Intermediate vSphere setting. It could additionally make the most of a slower however cheaper storage answer (NFS, for instance). Nevertheless, these deployment choices must be made solely after contemplating the variety of workloads that can 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 many others.). 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 tackle 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 a minimum of these permissions.
  5. Carry out all of the community configurations essential to make the vCenter accessible from the tenant website. 

TipIn the course of the preliminary setup wizard, contemplate enabling the Enable entry from Cloud setting, which is able to allow you to configure the migration from the cloud website. 

Supply Web site

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

Probably 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 doable to transform a Hyper-V VM utilizing two strategies:

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

A call have to be made based mostly on the Visitor OS distribution, its compatibility with vCenter Converter Standalone, and another components, resembling downtime, the necessity to modify the community configuration, and many others.

In case any configuration adjustments to the Visitor OS are required in the course of the migration (resembling community reconfiguration, pc title change, and many others.), then VMware instruments can be necessary to be put in. Please seek advice from the Considerations part for extra info on what is required.
