Smart phones SSL impact after Exchange 2010 to Exchange 2013 migration.

Hello,

I am in the process of migrating Exchange 2010 to Exchange 2013.  The environment is as follows:

CAS:      Exchange 2010 SP3 on Windows 2008 R2
MBX:      Exchange 2010 SP3 on Windows 2008 R2

CAS:      Exchange 2013 on Windows 2012 R2
MBX:      Exchange 2013 on Windows 2012 R2

•      Active Directory and Schema has been updated to allow the introduction of Exchange 2013.
•      Exchange 2013 has been installed on the new servers on the domain.
•      No issues were noted for client workstations.  Therefore Service Connection Point has not been changed.  Should Service Connection Point be changed using “Set-ClientAccessServer –Identity…” even if there have been no issues?
•      My next step is to Export the SSL certificate from 2010 and import to 2013.  On this standpoint I have a question.  
o      We have several users that use Smart Phones for email connectivity.  With no additional changes, will their phones still work when their mailbox has been moved to 2013 server?  
In the past, when moving from 2003 to 2010, I had taken the following action:
      Created new SSL for the new server.
      Created separate “A” record and published new server.
      Had users change their Smart Phone settings to use the new public host name.
o      That being said, can I continue on the steps to use the current SSL Certificate, or would it make better sense to create and assign a new SSL certificate.  My primary concern at this time is the appropriate manner in which to approach possible issues with Smart Phones.

Thanks in advance for your assistance.

Regards,
Rudy

When you introduce Exchange 2013 into the environment you need to make sure that you are proxying/redirecting from the newest Exchange server. So for mobile phone you will need to configure your ActiveSync virtual directories to hit the Exchange 2013 server which will then redirect or proxy (based on where the mailbox is located) and it will make the activesync connection.

If you have not looked at the Exchange Server Deployment Assistant I suggest you reference it. It will provide you with all of the high level steps for this migration.
