DRAG DROP
You have an Exchange Server 2016 organization. The organization has two Mailbox servers named EX01 and
EX02. Both servers are members of a database availability group (DAG) named DAG01.
A mailbox database named DB01 is replicated to EX01 and EX02.
You plan to move the database file and the transaction logs of DB01 to a new location.
You create a new folder structure on EX01 and EX02 to store the DB01 database file and transaction logs.
You need to complete the move. The solution must minimize the amount of network traffic between EX01 and
EX02.
You dismount DB01.

Hi,
Set-MailboxDatabase do nothing here.
First of all run Move-ActiveMailboxDatabase on EX01. Otherwise, how we know to remove DB01 from DAG on Ex02 or ExO1 ?
When you remove database copies, current server only holds the working database. For other servers, you have to create a copy later after the path has been moved. Therefore, Move-ActiveMailboxDatabase is not needed.
This is correct answer.
Technet Reference: (Move the mailbox database path for a mailbox database copy)
https://technet.microsoft.com/en-us/library/dd979782(v=exchg.160).aspx
It says : “You dismount DB01.”
AND
https://technet.microsoft.com/en-us/library/bb124742(v=exchg.160).aspx
“If the database is currently dismounted, it isn’t remounted upon completion.”
SO
– remove copy
– move-databasepath on EX1
– mount on EX1
– move on ex2
