This step-by-step guide provides instructions on creating a Migration Plan for migrating Virtual Machines (VMs) from VMware to OpenStack.
Before creating a Migration Plan, ensure the following prerequisites are met:
Access to the VMware environment.
OpenStack environment configured and accessible.
A clear understanding of the VMs you intend to migrate.
Log in to the OpenStack Dashboard (Horizon):
Use your credentials to log in to the OpenStack Dashboard.
Navigate to the VMware Migration section:
In the OpenStack Dashboard, locate and click on the VMware Migration under the Project tab.
Initiate Plan Creation:
Within VMware Migration, find the Create button to start creating a Migration Plan.
This may take some time to load as it connects to the vCenter and fetches all the accessible VM information.
Provide Plan Details:
Enter a unique and meaningful name for the Migration Plan.
Optionally, add a detailed description to provide context for the plan.
Select VMs for Migration:
Browse the list of available VMware VMs under the Migration Plan VMs tab.
Select the VMs that you intend to migrate as part of this plan.
Save the Migration Plan:
Click the Create button to save the Migration Plan after providing the necessary details and selecting VMs.
Optional: Modify Plan Details:
If needed, revisit the Migration Plan to modify details, add or remove VMs.
You can do that by clicking the Edit button in the drop-down Actions for that Migration Plan.
Review the Migration Plan:
To ensure all details are accurate and complete for the Migration Plan, click the created Migration Plan.
It will take you to the VMware Migration Plan Detail page where you can review the VMs and check additional information about those VMs.
Proceed with Discovery and Migration:
After creating and finalizing the Migration Plan, users can proceed with the "Discover VMs" operation to collect resource information, and subsequently initiate the actual migration.
Congratulations! You have successfully created a Migration Plan for migrating VMs from VMware to OpenStack. Ensure to review and validate the plan details before proceeding with the actual migration steps.
A Migration Plan is a structured and pre-defined set of instructions that outlines the process and details for migrating Virtual Machines (VMs) from a VMware environment to OpenStack. It serves as a blueprint for orchestrating the migration, including the selection of VMs, and managing the overall migration workflow. Each plan may have a name and may include a description to provide additional context and easy identification. Migration Plans are created and managed by users to ensure a systematic and controlled migration process.
To initiate the migration process, users must create a Migration Plan:
Provide a name and description for the plan.
Select VMs from the list of VMware VMs. This list does not include the VMs which are already part of a Migration Plan.
Any modification to the plan requires users to:
Revisit the plan details for updates.
Execute the "Discover VMs" call to fetch and update resource information in the Trilio service DB.
Failure to perform a "Discover VMs" after plan modification can lead to unexpected outcomes.
Discover VMs is an operation within the migration process that involves querying and collecting resource information from VMware for the VMs included in a Migration Plan. This operation is crucial for maintaining up-to-date details about the VMs, such as configuration, networking, and storage.
After creating or modifying a Migration Plan, users must:
Trigger the "Discover VMs" operation.
This operation collects resource information of VMs in the plan from VMware and stores it in the WLM service DB.
"Discover VMs" must be called every time the plan is updated to ensure accurate information for migration. It ensures accuracy in subsequent migration steps and helps prevent unexpected outcomes due to outdated information.
The user can also delete a Migration Plan if required. But it will need all the initiated migrations to be deleted. Refer to this page for deleting the initiated migrations for more information.
