Migrating Exchange 2013 Transaction logs to separate drive location before configuring DAG ?

I had this question after viewing Installing CAS role for the existing Mailbox server ?.

Hi All,

Before configuring a DAG on my newly configured Exchange Server 2013 Standard SP1, I wonder if it is possible to separate the Database and the Transaction logs drive ?

Since at the moment Circular logging is enabled in all mailbox DB, do I need to turn it off first and then move the small Transaction logs then configure it with Powershell perhaps ?

The new server: Mailbox role only in production for 1200 users.
Windows Server 2012 R2 Std
Exchange Server 2013 Standard SP1
PRODMBX20-VM
C:\ - OS - 120 GB
D:\ - PRODMBX20-VM-DB01 - 700 GB DB01 and its Tx Logs
E:\ - PRODMBX20-VM-DB02 - 700 GB DB02 and its Tx Logs
F:\ - PRODMBX20-VM-DB03 - 700 GB DB03 and its Tx Logs
G:\ - PRODMBX20-VM-DB04 - 700 GB DB04 and its Tx Logs
H:\ - PRODMBX20-VM-DB05 - 700 GB DB05 and its Tx Logs
I'm planning to create L:\ - PRODMBX20-VM - 500 GB Transaction Logs drive for all DB1-5 but is it possible or supported configuration for DAG or not in Exchange 2013 Standard edition ?


AD Site: Head_Office
The new server to be configured as DAG with the above [This server is different AD sites & location from the two above]:
Windows Server 2012 R2 Std
Exchange Server 2013 Standard SP1
PRODMBX30-VM
C:\ - OS - 120 GB
D:\ - PRODMBX30-VM-DB01 - 700 GB DB01 [still empty as place holder]
E:\ - PRODMBX30-VM-DB02 - 700 GB DB02 [still empty as place holder]
F:\ - PRODMBX30-VM-DB03 - 700 GB DB03 [still empty as place holder]
G:\ - PRODMBX30-VM-DB04 - 700 GB DB04  [still empty as place holder]
H:\ - PRODMBX30-VM-DB05 - 700 GB DB05  [still empty as place holder]
L:\ - PRODMBX30-VM - 500 GB Transaction Logs drive for all DB1-5 [still empty as place holder]

Thanks in advance,

There will be downtime when you try to change the logs folder.
Here is the command
Move-Databasepath "Database1" –EdbFilepath "C:\Newlocation\Database1.edb" –LogFolderpath "C:\Newlocation"

Open in new window


if you want to keep the same database path and change only the logs folder use the same command with change in location of logs folder

This command will list you the edb file path and logs folder path
Get-MailboxDatabase "DatabaseName" | FL Name,*Path*

Open in new window

Hi Mas,

Is this supported configuration in the DAG on Exchange 2013 standard ?

At the moment Circular logging is enabled the log is quite small.

Shall I migrate the logs now before I setup the DAG or after the DAG configured for both servers ?
MASEE Solution Guide - Technical Dept HeadCommented:
If you want  to move you have to move before configuring DAG.
Circular logging should be disabled.

Enable DAC  on DAG.

OK, so is that additional switch o checkbox to tick when configuring IP-Less DAG with one vNIC on the mailbox server ?
