A person is looking to move to a new CMS where the site has about 20,000 products on the front-end website. Let us tell you when the site switches to a new CMA, as it sounds like the URLs will have to change. So the person asked on Twitter if he could redirect 20,000 URLs.
And he got the answer “yes.” He can proceed like this by making sure that the URL will not be the same. Along with this, the process should be automated, as John Mueller of Google said on Twitter. He also said that he did not expect to see any ranking changes when making CMS changes.

The below points will show you the different scenarios when you can use the 301 redirect:
- You are deciding to go from HTTP to HTTPS.
- If you are moving from the old domain to a new one.
- When you are optimizing the URL slugs for existing posts and pages.
- If you are moving to a new website platform and your pages will change from https://domain.com/page.html to https://domain.com/page/.
Mostly, the discussion surrounding the 301 redirect concerned whether the PageRank would transfer from the old URL to the new one. The inbound links that existed for the old URL would be automatically applied to the new URL.
