before you do anything with exchange 2013, you need to upgrade your 2010 server to SP3 before they can co-exist

if you are going to conexist with exchange 2010 you should be verify whether you installed exchange 2010 sp3 or not , if not, you should upgrade first then you can try to install atlease exchange 2013 cu1. cu2 is latest update .


Thanks

Yes it is more than enough. before. could you please confirm your organization strength that means how many mailbox required for your concern so that i can tell you how many mailbox server required.

Each site has one CAS server, it s more than enough.

its small environment, you can use one CAS\MBX\HUB, If you want redundancy, you can use

2 CAS- Each site one CAS with CAS Array
2 MBX- with DAG ( with in site or site resilency)
2 HUB- for load balance purpose

No CAS Array in Exchange 2013.
Are you planning to have a DAG in place? If so you should really have four servers, a DAG for each site, with the passive in the other location. Trying to do active/active isn't going to give you the result that you want.

Personally i would go with a four server design and a load balancer. All roles on all four servers.

Thanks, I will eliminate the HW balancer at this stage and I will do dns changes in case, can I have just three servers ( two in the primary site and one in DR ) with DAG between the three?

If you are going to have no users in the second site, then that would work. That will allow you to have active/active/passive with a load balancer. Just ensure that all three servers are scaled to take all of the users.

@sembee2, Yes, No CAS Array in exchange 2013, because no longer using RPC Client Access Service,  i thought Exchange 2010. sorry for typo error.

Last question before I accept , can I have one MBX/CAS in the primary and one MBX/CAS in the other location and add the third one later in the primary site.


Thanks

You can do it that way if you wish. Although with 1400 users on a new platform, I would prefer to have both the local servers in place from the word go.
