Sometimes your users may require you to redirect to their new site and even capture errors like 404, 401 in their old site and redirect to their new site. You can do it by doing the following.
Step 1: After clearing out all the old site, you may want to put in a redirection page. Can be a simple one line on a index.html
Step 2: To trap “missing or ghost directory and files” in the website of the user directory. For example the old site could be http://www.myoldsite.com/~me/
You may want to create a .conf file such as myoldsite.conf and placed it at /etc/httpd/conf.d and put in the following configuration.
Step 3: Update the httpd service.
For CentOS 7, it could be
# systemctl start httpd.service
