Please take a look at different migartion methods:
Cutover Migration: You can use this method if you have fewer than 2000 mailboxes. This method is supported for Exchange 2003, 2007 and 2010: https://technet.microsoft.com/en-us/library/dn771183.aspx
Staged Migration: You can use this method if you have more than 2,000 mailboxes: https://technet.microsoft.com/en-us/library/jj898486(v=exchg.150).aspx
Hybrid Migration: If you have Exchange 2010/2013 and more than 150-2,000 mailboxes, you should use this method: https://technet.microsoft.com/en-us/library/jj200581(v=exchg.150).aspx
Microsoft provides two helpful tools for planning migration, including Exchange Server Deployment Assistant, this tool give step-by-step instruction for greenfield deployments, coexistence deployments, and migration-focused deployments. Second tool is the Remote Connectivity Analyzer that lets you test your connectivity.
