So we're looking at setting DFS and migrating users from a domain that has the tendant domain in O365 to the new domain. &nbsp;I'd would think it is better to migrate users from old domain to new domain first then setup DFS? &nbsp;We also have to think about the onpremise Lync setup.<br />

What is your advice on all this? &nbsp;Sorry if I am missing some details so please ask me any questions on this.
