EXCH2013 and DAG settings

Hi Experts,

when I migrate a mailbox to the new server, the client will be informed to restart the outlook and then autodiscover makes the rest of the job. When I check the server setting, I can see the new GUID of the 1st EX2013 server.

Later I want to use a DAG with 2 or 3 EX2013 servers.
Can I do this later ? What about the Client Access GUID for internal clients ?
Do I have to change this to the DAG name ?

yes you can no problem, this GUID is mailbox related not DAG related it will be different for each mailbox.

when you add your new server make sure that the URLs are the same as the existing one and you will need to find a way to load-balance bertween the 2 servers (DNS round robin is ok for 2013 or a dedicated load balancer)

Just to confirm, I can do the DAG later, lets say after I have moved all mailboxes ?

The DAG name is not a client access array name , right ?

yes you can after and in 2013 there is no such thing as CAS Array Name anymore that's why it is so easy to do it

ok I understand.

on my internal DNS I also have to change AUTODISCOVER and MAIL to my new IP address ->EX2013.
But what happens, if the first EX2013 server goes offline ?
What happens with my internal AUTODISCOVER and MAIL entries ?

that's why i told you you need to find a way to load balance

if you have a dedicated load balancer, it will take care of that, with DNS round robin the client will get disconnected and then pickup the other record and reconnect to the working server so mail and autodiscover will have 2 entries one for each server

OK,
I have a Firewall from FORTINET. A loadbalancer is included but I think just for external connection to internal.
I am not sure.
With DNS RR you mean multiple entires of MAIL and AUTODISCOVER in my DNS zone ?

yes fortinet is for external

for internal you need to have to have another way to load balance if you want to go for DNS round robin you will have 2 records for mail one pointing to the IP of server1 and one pointing to the IP of server2 same for autodiscover

Ok you helped me a lot.
Now it is clear.
First I will go for DNS RR and next year we buy a nice HLB from KEMP.
