Hi @sakuraime ,

> may I know the above steps , are also applicable to multi-domain DAG ???

No, according to MS document, for availability groups and WSFC clusters that are not joined to the same domain, use certificates to make the distributed availability group work, much in the way that you might create an availability group for a domain-independent availability group. To see how to configure certificates for a distributed availability group, follow steps 3-13 under Create a domain-independent availability group.

Best regards,
Cathy
