Configuring Exchange Server DAG mailbox replication to different drive on each server ?

Hi All,

I'm on Exchange Server 2013 SP1 Standard edition running DAG for 2x Mailboxes server on IP-less configuration as per http://msexchangeguru.com/2014/03/21/e2013sp1-ip-less-dag/

However, I cannot seems to modify the path for the replica copy of the Database in the passive server to point to the different drive letters ?

Data Center 1
PRODMBX1-VM - Mailbox Server
Active DB:
Mailbox-DB1 Path D:\Mailbox-DB\1 for both logs & database
Mailbox-DB3 Path E:\Mailbox-DB\3 for both logs & database
Mailbox-DB5 Path F:\Mailbox-DB\5 for both logs & database

Passive DB:
Mailbox-DB2 Path G:\Mailbox-DB\2 for both logs & database
Mailbox-DB4 Path H:\Mailbox-DB\4 for both logs & database

Data Center 2
PRODMBX2-VM - Mailbox Server
Active DB:
Mailbox-DB2 Path E:\Mailbox-DB\2 for both logs & database
Mailbox-DB4 Path F:\Mailbox-DB\4 for both logs & database

Passive DB:
Mailbox-DB1 Path G:\Mailbox-DB\1 for both logs & database
Mailbox-DB3 Path H:\Mailbox-DB\3 for both logs & database
Mailbox-DB5 Path I:\Mailbox-DB\5 for both logs & database

How to change the destination of the replica copy ?
and is it possible to delay the mailbox Database replication so that it can be done after hours only one mailbox DB at a time ?

Any help would be greatly appreciated.

Thanks,
