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 achieved previous to beginning the method whereas the VM is working on the supply or after it’s transformed on the intermediate website.
Circulation
The steps are as follows:
- Put together the vacation spot cloud if it doesn’t have VMware Cloud Director Availability working.
- Deploy and configure the intermediate website.
- Deploy vCenter Converter Standalone and its elements accordingly on the supply website.
- Convert a VM/bodily machine to the intermediate website.
- Confirm all of the properties (GuestOS kind, model, SCSI controller, and many others.) are appropriately populated by means of the vSphere UI.
- (Non-obligatory) Energy on the VM if wanted.
- Configure the migration utilizing VMware Cloud Director Availability.
- (Non-obligatory) If the VM is powered off, carry out a handbook sync.
- (Non-obligatory) 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 Website
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 purpose, it’s not, 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’ll be able to seek advice from the VMware Cloud Director Availability Reference Structure and documentation for particular strategies 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 Website
The intermediate website might be deployed and managed by the Cloud Supplier or by the tenants of their knowledge middle. Which choice is extra appropriate should be decided primarily based on a number of components similar to value, obtainable {hardware}, workload criticality, and many others.The location should run vSphere 6.7U3 (already previous Finish of Common Assist), 7.0, 7.0U1, 7.0U2, or 7.0U3. There should be at the very least one present 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 website)
- vSphere Necessities Plus
- vSphere Normal
- vSphere Enterprise
- vSphere Enterprise Plus
- vSphere Desktop
The vCenter tackle should 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 will also be a vSphere surroundings working 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.
Possibility #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 is likely to be difficult.
Tip: To optimize the fee accrued to the Cloud Supplier by working the Intermediate website, the transformed VMs can stay powered off and immediately be migrated to the cloud(Chilly Migration). It would 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 might probably additionally make the most of a slower however cheaper storage resolution (NFS, for instance). Nevertheless, these deployment choices ought to be made solely after contemplating the variety of workloads that will likely 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 website able to accommodate the transformed VMs.
- Deploy and put together the vSphere infrastructure based on the chosen design (configure networking, storage, and many others.). 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 tackle 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 at the very least these permissions.
- Carry out all of the community configurations essential to make the vCenter accessible from the tenant website.
Tip: Throughout the preliminary setup wizard, think about enabling the Enable entry from Cloud setting, which is able to allow you to configure the migration from the cloud website.
Supply Website
Due to the varied sources supported by vCenter Converter Standalone (see Limitations for extra info) and every has totally different necessities, there isn’t any beneficial structure for the supply website.
Essentially the most appropriate conversion strategy ought to be decided by the machine (digital or bodily) proprietor based on 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 should be made primarily based on the Visitor OS distribution, its compatibility with vCenter Converter Standalone, and another components, similar to downtime, the necessity to modify the community configuration, and many others.
In case any configuration modifications to the Visitor OS are required throughout the migration (similar to community reconfiguration, pc identify change, and many others.), then VMware instruments will likely be obligatory to be put in. Please seek advice from the Concerns part for extra info on what is required.
