Resource Limits

The Machine Type and Storage resources are calculated automatically based on the sources selected for migration. The fields are not editable. After attempting to edit them, the system sets the values to the automatically calculated.

The ranges below the values reflect the requirements and limitations of the target platform and engine. The values exceeding the range are highlighted in red.

In the Database Instances tab, when attempting to add an extra source that would exceed the resource limits of an existing instance, both the instance name in the Instance list and the Confirm button become gray and disabled, and the following message appears:

The instance has reached the limit of its resources.
