Dear @john john Pter,
Thank you for posting your question in the Microsoft Q&A forum.
I completely understand the confusion, especially with newer blog posts mentioning “GA with no scale limitations” and suggesting there might be a UI option.
Based on the most recent Microsoft documentation and announcements, the only supported way to rename your SharePoint and OneDrive domain is still via PowerShell using the Start‑SPOTenantRename cmdlet. For reference: Change your SharePoint domain name
This applies even after the October 2025 general availability updates and the expansion to larger tenant sizes. Microsoft has not released any UI-based rename feature in the SharePoint Admin Center. The rename process, whether Standard (≤10,000 sites) or Advanced (SAM‑licensed for large tenants), continues to be initiated using PowerShell.
Based on the article you provided, tenant rename is now available to all tenants regardless of size. Previously, tenant renamed was limited to organizations with 10,000 sites or fewer. Now, Microsoft has announced general availability with no site count limit for Advanced Tenant Rename.
I hope this information is helpful. If you have any questions or if I misunderstand anything, please feel free to reach out.
Thank you for your patience and your understanding. I'm looking forward for your reply.
