Do you mean "migrated"?
If so, those migrated keys' descriptors should show among the results of listdescriptors command.
Copy all of your descriptors including the additional information and import all of those with importdescriptors command just like how you imported the previous two.

However, this will be a tedious task if your legacy wallet was not HD and you've previously used a lot of keys since each of your public/private keys are imported as "combo" descriptors.
In that case, you'll need to import all of those to track their past and future transactions.
