<font size="3">For a <span data-end="23" data-start="6" style="">company split</span>, the first step in <span data-end="73" data-start="43" style=""><a href="https://www.cloudbik.com/solutions/microsoft-365-tenant-migrations/" target="" title="">tenant-to-tenant migration</a></span> is <span data-end="126" data-start="77" style="">planning identity, scope, and domain strategy</span>.</font>

<font size="3">Start by defining <span data-end="211" data-start="147">which users, mailboxes, OneDrive, SharePoint, and Teams data</span> will move to the new tenant. Next, prepare the <span data-end="319" data-start="259">target tenant (Entra ID, licenses, security, compliance)</span> and plan the <span data-end="358" data-start="333">custom domain cutover</span> carefully to avoid mail flow disruption.</font>

<font size="3">Only after this should data migration begin—typically <span data-end="520" data-start="457">OneDrive & SharePoint first, then Teams, and mailboxes last</span>.</font>
