How to Use Migration Assessment
This tutorial covers two methods to assess your VMware environment for migration to OpenShift Virtualization.
Choose your assessment method:
- RVTools Flow - Upload an existing RVTools Excel export for instant assessment
- Discovery Agent Flow - Deploy an OVA to vCenter for live discovery
RVTools Flow
Upload an existing RVTools export file for instant assessment. Watch the video tutorial below:
Prerequisites: RVTools File Requirements
Before uploading your RVTools export, ensure your Excel file meets the following requirements. The migration assessment tool validates your RVTools export and will report errors or warnings based on what’s present.
Hard Requirements (Errors)
If these are missing, the upload will fail. All of these reside in the vInfo sheet:
| Requirement | Why? |
|---|---|
| vInfo sheet must have at least 1 row | No VMs means there is no inventory to plan |
| Column VM ID must not be null/empty | Used as the primary unique identifier for VMs |
| Column VM (Name) must not be null/empty | Used to identify and display the VM |
Soft Requirements (Warnings)
The following sheets are checked, but if they are empty or missing, the tool will only issue a warning. The inventory will still be built, but specific data points will be blank:
| Sheet | Impact if Missing |
|---|---|
| vHost | Host-related info will be unavailable |
| vDatastore | Storage/datastore info will be missing |
| vNetwork | Network configuration details will be missing |
| vCPU | Detailed CPU metrics (like core counts) will be missing |
| vMemory | RAM allocation details will be missing |
| vDisk | Disk size and provisioning data will be missing |
| vNic | Network interface details (IPs/MACs) will be missing |
Export your RVTools data with all sheets enabled to ensure the most comprehensive migration assessment.
