You can discover extra in regards to the supported Operating Systems right here.
For any conversion limitations, please verify right here.
Considerations
To apply any Guest Customization properties on the migrated VM on the vacation spot website, VMware instruments must be put in earlier than the migration to the tenant group is initiated. It might be accomplished previous to beginning the method whereas the VM is working on the supply or after it’s transformed on the intermediate website.
Flow
The steps are as follows:
- Prepare 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.
- Verify all of the properties (GuestOS kind, model, SCSI controller, and so on.) are accurately populated by the vSphere UI.
- (Optional) Power on the VM if wanted.
- Configure the migration utilizing VMware Cloud Director Availability.
- (Optional) If the VM is powered off, carry out a handbook sync.
- (Optional) Configure the Recovery settings – Network configuration (Re-IP), Guest Customization.
- Initiate the migration.
The non-optional steps are marked with their numbers on the diagram.
Destination Site
Since 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 observe the VMware Cloud Director documentation to set it up correctly.
The first obligatory requirement is to have all of the VMware Cloud Director Availability home equipment deployed and configured on the VMware Cloud Director cloud.
You can confer with the VMware Cloud Director Availability Reference Architecture and documentation for particular recommendations and directions on how you can do it.
The cloud website is prepared for migrations when VMware Cloud Director Availability is prepared, and its Service Endpoint deal with is accessible.
Intermediate Site
The intermediate website might be deployed and managed by the Cloud Provider or by the tenants of their information middle. Which possibility is extra appropriate have to be decided based mostly on a number of components corresponding to price, obtainable {hardware}, workload criticality, and so on.The website should run vSphere 6.7U3 (already previous End of General Support), 7.0, 7.0U1, 7.0U2, or 7.0U3. There have to be at the least one current person with the next permissions required by vCenter Converter Standalone.
One of the next vSphere licenses ought to be utilized:
- vSphere Evaluation license (if the migration is achieved inside 60 days of provisioning the vSphere intermediate website)
- vSphere Essentials Plus
- vSphere Standard
- vSphere Enterprise
- vSphere Enterprise Plus
- vSphere Desktop
The vCenter deal with have to be accessible from the vCenter Converter Standalone machine.
There are two attainable 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 Organization within the VMware Cloud Director cloud. It can be a vSphere setting 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 Organization within the VMware Cloud Director cloud.
Option #1 is appropriate when the Cloud Provider 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. Options #2 is appropriate when the Cloud Provider provides a managed service as a result of limiting the visibility of tenants solely to their assets in a shared vSphere setting is perhaps difficult.
Tip: To optimize the fee accrued to the Cloud Provider by working the Intermediate website, the transformed VMs can stay powered off and immediately be migrated to the cloud(Cold 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 setting. It can even make the most of a slower however cheaper storage answer (NFS, for instance). However, these deployment selections ought to be made solely after contemplating the variety of workloads that might be migrated. Also, this method may result in a greater 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 response to the chosen design (configure networking, storage, and so on.). VMware Cloud Foundation 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 deal with and Organization administrator credentials (relying on the design, the credentials ought to be for a tenant or system Organization).
- Create a person for vCenter Converter Standalone with at the least these permissions.
- Perform all of the community configurations essential to make the vCenter accessible from the tenant website.
Tip: During the preliminary setup wizard, take into account enabling the Allow entry from Cloud setting, which is able to allow you to configure the migration from the cloud website.
Source Site
Because of the varied 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 website.
The best suited conversion method ought 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 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 Guest OS distribution, its compatibility with vCenter Converter Standalone, and another components, corresponding to downtime, the necessity to modify the community configuration, and so on.
In case any configuration adjustments to the Guest OS are required through the migration (corresponding to community reconfiguration, laptop identify change, and so on.), then VMware instruments might be obligatory to be put in. Please confer with the Considerations part for extra data on what is required.
Automation
Several steps might be automated to scale back the quantity of handbook work.
- Shipping the binaries and silent set up of VMware instruments. (Link for Windows & Link for Linux)
