I need help hiding an old site address

Could you please provide the old website address and the new website address, and confirm whether the old website is still live?
It would also be helpful to know what you mean by “hiding” the old address — for example, is it still appearing in Google search results when people search for the business?
This will allow me to understand the current situation and confirm what can be done.

can you please share your existing site url?

Hi, could you share the old site address and the new site address, and confirm whether you still have any access at all to the old website/domain or its Google Search Console account?

Can you send me the old and new website addresses so I can see exactly how they are currently appearing?
