Thanks for sharing your professional idea on the TechNet forum (http://social.technet.microsoft.com/Forums/sharepoint/en-US/07074c6d-731f-457f-b3ac-b2a2c943117d/migration-to-sharepoint-2013?forum=sharepointadmin&prof=required)
I have been think of the way to migrate SharePoint 2010 to SharePoint 2013. I believe your migration method should work on migrating to Azure SharePoint 2013 which I am going to do. The method you pointed out in the forum question is quite straightforward to understand and I can see the big picture of the migration though I am not sure one thing. If you do not mind, would you please share your opinion for my case.
I have on premise Exchange Server 2007 SP3 integrates with the current on premise SharePoint Server 2010 and will continue to use on premise Exchange 2007 (I think as long as the VPN (Site to Site) connection between on premise and Azure, it should work. Currently Azure doesn't let us to use Exchange server on Azure, so I think this is the only way that Azure SharePoint 2013 integrates with Exchange Server.
Please correct me if I am wrong and if you have any other idea, would you please share it with me?
Last but not in the least, I visited your website and found out very informative and practical. Thank you very much for sharing your idea.
