Understand Site Availability During a Root Site Swap
Clarification on what remains accessible and what experiences temporary downtime during the process.
When you swap the SharePoint Online root site, the process is designed to minimize disruption to your tenant. Testing and official documentation confirm that swapping the root site does not cause a tenant-wide outage. Other SharePoint site collections remain fully functional and accessible to users.
However, the current root site and the newly designated replacement root site may experience temporary unavailability while the URL routing is updated.
Navigate to any other SharePoint site collection. These will remain accessible and operational throughout the root site swap.
The main SharePoint start page remains active and accessible to users, ensuring they can still find their frequently visited sites.
Expect brief HTTP 404 errors or redirection delays specifically on the original root site and the new target site while the background swap process completes.

Frequently Asked Questions
How long does a SharePoint root site swap take?
The time required for a root site swap depends on the size and complexity of the sites involved, but the actual URL redirect usually takes only a few minutes. Full search indexing for the newly swapped site may take slightly longer.
Can I revert a root site swap if something goes wrong?
There is no direct 'undo' button. If you need to revert, you must perform another root site swap, swapping the current root site back with the archived original root site.
Will users lose permissions during a root site replacement?
No, site permissions are retained during the swap. The target site replaces the root site URL, but its existing permissions and content structures remain intact.
Does a root site swap affect OneDrive for Business?
No, user OneDrive for Business URLs and files are completely separate from the tenant root site and are not impacted during a root site swap.
