Accuracy levels of cloud migration simulation
The following table explains the accuracy levels that are associated with the resizing recommendations for the proposed or target instances in the migration simulation results page. You can use the information in the Probable reason and Probable resolution columns to understand the cause of the levels and the actions that you can take to improve them.
Icon/ Accuracy level | UI message | Probable reason | Probable resolution |
---|---|---|---|
- Very Low | At least one mandatory configuration metric is not available. Simulation is performed based on the other available configuration metrics. | One or more required configuration metrics of the source server are not available. In most cases, the storage related metric is unavailable. |
|
- Low | Although utilization-based strategy was selected, simulation is based on lift-and-shift strategy because at least one mandatory utilization metric is not available. | One or more utilization metrics of the source server are not available. Only configuration metrics are available. |
|
- Medium | Although balanced behavior was selected, simulation is based on aggressive behavior because detailed statistics for hourly data samples are not available for the server. |
The CPU_UTILMHZ_HM metric is missing. Utilization metrics of the source server are collected at hourly granularity.

Although conservative behavior was selected, simulation is based on aggressive behavior because detailed statistics for hourly data samples are not available for the server. | |||
- Medium | Simulation is not considering CPU benchmark because it is not available. | The estimated CPU benchmark (SPECint_rate2006) value is not available for the source VM. |
|
- High | Although balanced behavior was selected, simulation is based on 15 minutes detail samples. Detailed statistics for hourly data samples are not available for the server. |
The CPU_UTILMHZ_HM metric is missing. Utilization metrics of the source server are collected at 15-minutes granularity. Information: The accuracy level is High as compared to the earlier scenarios because the 15-minute data samples are available as compared to hourly granularity.

Simulation is based on aggressive behavior, as requested. | The metrics that are required for the selected behavior are available and the recommendation is generated as expected. | No action is required. | |
- Very High | Simulation is based on balanced behavior, as requested. | The metrics that are required for the selected behavior are available and the recommendation is generated as expected. | No action is required. |
Simulation is based on conservative behavior, as requested. |
