Concerns
To use any Visitor Customization properties on the migrated VM on the vacation spot web site, VMware instruments have to be put in earlier than the migration to the tenant group is initiated. It may be executed previous to beginning the method whereas the VM is operating on the supply or after it’s transformed on the intermediate web site.
Circulate
The steps are as follows:
- Put together the vacation spot cloud if it doesn’t have VMware Cloud Director Availability operating.
- Deploy and configure the intermediate web site.
- Deploy vCenter Converter Standalone and its elements accordingly on the supply web site.
- Convert a VM/bodily machine to the intermediate web site.
- Confirm all of the properties (GuestOS kind, model, SCSI controller, and so forth.) are accurately populated via the vSphere UI.
- (Non-compulsory) Energy on the VM if wanted.
- Configure the migration utilizing VMware Cloud Director Availability.
- (Non-compulsory) If the VM is powered off, carry out a guide sync.
- (Non-compulsory) Configure the Restoration settings – Community configuration (Re-IP), Visitor Customization.
- Provoke the migration.
The non-optional steps are marked with their numbers on the diagram.
Vacation spot Web site
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 purpose, 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 check with the VMware Cloud Director Availability Reference Structure and documentation for particular ideas and directions on easy methods to do it.
The cloud web site is prepared for migrations when VMware Cloud Director Availability is prepared, and its Service Endpoint handle is accessible.
Intermediate Web site
The intermediate web site might be deployed and managed by the Cloud Supplier or by the tenants of their information heart. Which choice is extra appropriate should be decided primarily based on a number of elements comparable to value, obtainable {hardware}, workload criticality, and so forth.The positioning should run vSphere 6.7U3 (already previous Finish of Basic Assist), 7.0, 7.0U1, 7.0U2, or 7.0U3. There should be no less than one current consumer with the next permissions required by vCenter Converter Standalone.
One of many following vSphere licenses ought to be utilized:
- vSphere Analysis license (if the migration is achieved inside 60 days of provisioning the vSphere intermediate web site)
- vSphere Necessities Plus
- vSphere Commonplace
- vSphere Enterprise
- vSphere Enterprise Plus
- vSphere Desktop
The vCenter handle should be accessible from the vCenter Converter Standalone machine.
There are two attainable choices for the deployment of the Intermediate vSphere atmosphere:
- 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 will also be a vSphere atmosphere operating on the tenant’s infrastructure and managed by them.
- 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.
Choice #1 is appropriate when the Cloud Supplier provides 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 provides a managed service as a result of limiting the visibility of tenants solely to their sources in a shared vSphere atmosphere is perhaps difficult.
Tip: To optimize the fee gathered to the Cloud Supplier by operating the Intermediate web site, the transformed VMs can stay powered off and immediately be migrated to the cloud(Chilly Migration). It should require a guide sync after the migration is configured however will enable even a deployment with much less compute sources for the Intermediate vSphere atmosphere. It will possibly additionally make the most of a slower however cheaper storage answer (NFS, for instance). Nevertheless, these deployment choices ought to be made solely after contemplating the variety of workloads that might be migrated. Additionally, this strategy may result in a larger downtime interval for the transformed workload.
Deployment steps
These steps should be adopted to get the intermediate web site able to accommodate the transformed VMs.
- Deploy and put together the vSphere infrastructure in keeping with the chosen design (configure networking, storage, and so forth.). VMware Cloud Basis can be utilized for automating the deployment course of.
- Deploy the VMware Cloud Director Availability On-Premises to Cloud Director Replication equipment following the steps offered within the documentation.
- 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 ought to be for a tenant or system Group).
- Create a consumer for vCenter Converter Standalone with no less than these permissions.
- Carry out all of the community configurations essential to make the vCenter accessible from the tenant web site.
Tip: Throughout the preliminary setup wizard, contemplate enabling the Enable entry from Cloud setting, which can allow you to configure the migration from the cloud web site.
Supply Web site
Due to the assorted sources supported by vCenter Converter Standalone (see Limitations for extra data) and every has completely different necessities, there isn’t a advisable structure for the supply web site.
Probably the most appropriate conversion strategy ought to be decided by the machine (digital or bodily) proprietor in keeping 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 choice should 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 forth.
In case any configuration adjustments to the Visitor OS are required through the migration (comparable to community reconfiguration, laptop identify change, and so forth.), then VMware instruments might be necessary to be put in. Please check with the Concerns part for extra data on what is required.
