The Instance Configuration dialog
Resource Limits
The Machine Type and Storage resources are calculated automatically based on the sources selected for migration but can be manually set to a greater value.
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.
Remove sources until the limitation indicators disappear in order to proceed.
