问题
I'm planning to move an old website to a new domain. Then, I would like to use the old domain with a completely brand new different website.
So after the move there would be 2 different websites:
Old website --> brandnewdomain.com
New website --> olddomain.com
The problem I'm having is that how can I 301 redirect all URLs from the old website to a new domain to keep the visitors flow from search engines and at the same time use the old domain with a new website? For example I can't 301 redirect the main domain URL when I want to use it for a new website. And also I can imagine more URL conflicts occur.
Have you been in a similar situation? What would you do?
