How to switch domain name/URL of the sharepoint

[Lea_b20]

Hello, 

So I already have a sharepoint, let's call it Sharepoint A. I'm creating a new sharepoint page, let's call it Sharepoint B. I would be able to replace Sharepoint A by Sharepoint B, keeping the same URL, so that people would not be confused by all the different sharepoints. How can I do that? 

Thank you in advance, 

Léa

@Lea_b20 I think you need to look at https://docs.microsoft.com/en-us/sharepoint/change-site-address

@Lea_b20 If you are looking to update the site URL https://domain.sharepoint.com/<<siteurl>> follow the approach suggested by RobElliott

Microsoft recently rolled out the update to rename Microsoft 365 tenant to update your domain name. If that is what you are looking for https://petri.com/how-to-rename-your-sharepoint-domain-in-microsoft-365/

This has potential to break many things, I will recommend to do your due diligence if that is what you are looking at.
