Beginning migration to 2013
We are in the process of migrating from ex2007 to ex2013. We will continue to use Outlook 2007 client but access OWA 2013.
We are currently running EV10.4. I will be installing the 10.4 hotfix for mixed environment compatibility.
What else needs to be done on within EV and/or installed on the Exchange 2013 servers to successfully migrate mailboxes to ex2013 and successful access to vaulted messages.
On a related topic, in preparation for the migration, we recently migrated ISA rules to barracuda load balancers. OWA clients are redirected to ex2013 which routes them to ex2007 if the mailbox is still on 2007. After doing this, vaulted messages are not available via OWA. It was our understanding this is a simple reroute.
I did not install the current EV environment so I'm just becoming familiar with EV deployment. Any direction is much appreciated.
You can migrate user's mailboxes from Ex2k7 to 2k13 and place 'SynchInMigrtion' mode dword value 1 as directed by Adviser, you can take reference information from http://www.symantec.com/docs/TECH48928
EV servers needs to be published for EV action if users accessing via OWA(OR RPC anywhere). There are configuration changes as EV work with OWA 2013 only via office mail app. So you need to configure mailbox and define external-internal EV URL as well.
The details on configuration steps can be found in TN http://www.symantec.com/docs/HOWTO83364, it has few excellent video to understand how app work with Exchange 2013.
EV icons would not be visible in case of Exchange 2013 OWA access so icons should not be an issue but Barracuda should not stop other functionalities. You may wish to talk their support representative if anything breaks.
We can utilize single internet publish record if Barracuda allows web proxying. (we don't have any sort of certification for Barracuda as firewall). The rules & functionalities should work as mentioned in link below (this if UAG firewall).
