Issues
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.
Movement
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 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 so forth.) are appropriately populated via the vSphere UI.
- (Elective) Energy on the VM if wanted.
- Configure the migration utilizing VMware Cloud Director Availability.
- (Elective) If the VM is powered off, carry out a handbook sync.
- (Elective) 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
For the reason that supposed 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 isn’t, please comply with 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 confer with the VMware Cloud Director Availability Reference Structure and documentation for particular ideas and directions on do it.
The cloud website is prepared for migrations when VMware Cloud Director Availability is prepared, and its Service Endpoint handle is accessible.
Intermediate Web site
The intermediate website could be deployed and managed by the Cloud Supplier or by the tenants of their information middle. Which choice is extra appropriate should be decided based mostly on a number of components akin to price, out there {hardware}, workload criticality, and so forth.The positioning should run vSphere 6.7U3 (already previous Finish of Common Assist), 7.0, 7.0U1, 7.0U2, or 7.0U3. There should be no less than one current person with the next permissions required by vCenter Converter Standalone.
One of many following vSphere licenses needs to be utilized:
- vSphere Analysis license (if the migration is completed inside 60 days of provisioning the vSphere intermediate website)
- vSphere Necessities Plus
- vSphere Normal
- vSphere Enterprise
- vSphere Enterprise Plus
- vSphere Desktop
The vCenter handle should be accessible from the vCenter Converter Standalone machine.
There are two doable 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.
- 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 assets in a shared vSphere surroundings may be difficult.
Tip: To optimize the price gathered 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 would require a handbook sync after the migration is configured however will permit even a deployment with much less compute assets for the Intermediate vSphere surroundings. It could actually additionally make the most of a slower however cheaper storage resolution (NFS, for instance). Nevertheless, these deployment selections needs to be made solely after contemplating the variety of workloads that can be migrated. Additionally, this method would possibly result in a increased 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 in response to 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 supplied 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 needs to be for a tenant or system Group).
- Create a person 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 website.
Tip: Throughout 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 Web site
Due to the assorted sources supported by vCenter Converter Standalone (see Limitations for extra data) and every has totally different necessities, there isn’t a really helpful structure for the supply website.
Essentially the most appropriate conversion method needs to be decided by the machine (digital or bodily) proprietor in response to 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 should be made based mostly on the Visitor OS distribution, its compatibility with vCenter Converter Standalone, and another components, akin to downtime, the necessity to modify the community configuration, and so forth.
In case any configuration adjustments to the Visitor OS are required in the course of the migration (akin to community reconfiguration, laptop identify change, and so forth.), then VMware instruments can be obligatory to be put in. Please confer with the Issues part for extra data on what is required.
Automation
A number of steps could be automated to scale back the quantity of handbook work.
- Transport the binaries and silent set up of VMware instruments. (Hyperlink for Home windows & Hyperlink for Linux)
