Issues
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 working on the supply or after it’s transformed on the intermediate website.
Stream
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 parts accordingly on the supply website.
- Convert a VM/bodily machine to the intermediate website.
- Confirm all of the properties (GuestOS sort, model, SCSI controller, and so on.) are accurately populated via 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 guide 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
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 cause, it isn’t, please comply with 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 strategies and directions on the best way 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 may be deployed and managed by the Cloud Supplier or by the tenants of their knowledge middle. Which possibility is extra appropriate have to be decided based mostly on a number of elements reminiscent of price, obtainable {hardware}, workload criticality, and so on.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 not less than 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 Commonplace
- vSphere Enterprise
- vSphere Enterprise Plus
- vSphere Desktop
The vCenter tackle have to 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 may also be a vSphere atmosphere 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 affords 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 affords a managed service as a result of limiting the visibility of tenants solely to their assets in a shared vSphere atmosphere is perhaps difficult.
Tip: To optimize the associated fee collected 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 guide sync after the migration is configured however will enable even a deployment with much less compute assets for the Intermediate vSphere atmosphere. It may possibly additionally make the most of a slower however cheaper storage answer (NFS, for instance). Nonetheless, these deployment choices must be made solely after contemplating the variety of workloads that might be migrated. Additionally, this strategy would possibly result in a larger 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.
- Deploy and put together the vSphere infrastructure in line with the chosen design (configure networking, storage, and so on.). 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 must be for a tenant or system Group).
- Create a consumer for vCenter Converter Standalone with not less than these permissions.
- Carry out all of the community configurations essential to make the vCenter accessible from the tenant website.
Tip: Through 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 assorted sources supported by vCenter Converter Standalone (see Limitations for extra data) and every has completely 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 based mostly on the Visitor OS distribution, its compatibility with vCenter Converter Standalone, and another elements, reminiscent of downtime, the necessity to modify the community configuration, and so on.
In case any configuration adjustments to the Visitor OS are required in the course of the migration (reminiscent of community reconfiguration, laptop identify change, and so on.), then VMware instruments might be necessary to be put in. Please check with the Issues part for extra data on what is required.
Automation
A number of steps may be automated to scale back the quantity of guide work.
