What is the Best Practice or Procedure of Changing Mail Domain on FortiMail?

[FG-PioneerClient]

Hello,

I am wondering:

1.  Is there a Document or Procedure to change the existing Mail Domain Name to a new one ?

2. OR a Best Practice guid to do such migration from existing Domain Name to a new Domain Name ?

3. Are there known issues or concerns we should consider ?

Thanks N advance
