- Enable Outlook Anywhere on the Exchange 2007 server (if it is not already enabled - it may be).
- Assign all mailbox databases an Offline Address Book (once again, if this is not already the case).
- Disable IPv6 on the Exchange 2007 server (if the Exchange 2013 server will host both the Client Access and Mailbox roles).
- Create a legacy Exchange host name in DNS.
- Prepare storage. In my test environment, there is not much to do here. In a production environment, especially a large one, this could require much planning.
- Ensure that our client software (Outlook for example) is compatible with Exchange 2013.

Offline Address Book
Note: mailboxes created in the mailbox database inherit this setting.
If this were not the case, we could set the OAB like this (for example):
Set-MailboxDatabase "EX1\MBXDB1" -OfflineAddressBook "Default Offline Address Book"
1) the Exchange 2007 server holds both the Mailbox and Client Access roles.
2) the Exchange 2007 server has IPv6 enabled.
How to disable IPv6 or its components in Windows
Apparently, and according to the Exchange Server Deployment Assistant, we do not need to disable IPv6 entirely (the loopback interface can remain enabled).
Outlook Anywhere does not work if IPv6 is enabled on an Exchange Server 2007 multi-role server
Legacy Exchange name (DNS)
We should ensure that Outlook clients are compatible with Exchange 2013.
- Outlook 2003 is not compatible.
- Outlook 2007 is compatible with SP3 (and updates as of November 2012 or later)
- Outlook 2010 is compatible with SP1 (and updates as of November 2012 or later)
- Outlook 2013 is compatible.
Note: the version of Outlook used by my clients is Outlook 2010 SP2.
As for web browsers, Internet Explorer 9 is the oldest version that provides what is rated a "best" experience with Exchange 2013. For other browsers, and the level of experience, consult this article:

In my next blog post, and after several posts about "preparation", I will - finally - install Exchange 2013.
