Exchange 2013 migration between AD sites

Hello,

I am preparing a migration from one Exchange 2013 Cu6 server to another 2013 CU6 server in the same domain in a different  AD site. Each server is HT and MB server, hosting its own DB. There is no DAG between the 2 servers.

I am planning to use coexistence between the servers during the migration when I move mailboxes from one server to the other. The move should be transparent to the users. Outlook should detect the move and find it automatically.

I configured one namespace for all URLs, identical on both servers like "mail.organization.nl" for AS, OA, OWA, ECP and autodiscover.

Would this work? I read here it will: The article is referrning to a DAG spanned over 2 sites, which I do not have.

Any advice on performing this migration without issues?

Thanks
