Transfer Certificate from .net id to .com id

Hi
One of my colleagues is facing some issue while linking his microsoft learn account.
As he wants to register on Microsoft partner center his ".com" id is required.
We have created his .com id but he did his certification with .net id.
Now we try to link microsoft learn account of .com id to .net microsoft learn account.
But we are getting this :
So I think we are not able to link .com account with .net on microsoft learn.
Is there any way to transfer all Azure certification credentials to ".com" id?
******@netsmartz.net to ******@netsmartz.com
Kindly assist me in doing so.
As i need to register on Microsoft partner center.
Or suggest other way how can we do so.
