Google accepts 301 redirects of old sitemaps to new ones without any issues. However, Mueller still recommends submitting the new URL directly in Search Console or robots.txt to avoid any misunderstanding with crawlers. Bottom line: the redirect works, but it's better to explicitly declare the new sitemap.
What you need to understand
Why does Google tolerate a 301 redirect on the sitemap?
The logic is straightforward: Googlebot follows 301 redirects just as it would for any other URL. If the old sitemap redirects with a 301 to the new one, the bot understands that the resource has moved and adjusts its crawling accordingly.
This tolerance prevents penalizing websites that migrate or redesign their architecture without immediately updating all sitemap references. In practice, the engine adapts — but that doesn't mean it's the optimal solution.
What's the difference between submitting via Search Console and robots.txt?
Search Console allows you to manually declare the new sitemap URL in the dedicated interface. It's quick, but limited to GSC. The robots.txt file, on the other hand, exposes the sitemap to all crawlers that read the file — not just Google.
Declaring the sitemap in robots.txt with the Sitemap: directive remains the most universal and cleanest method. It guarantees that any respectful bot will find the information without having to follow a redirect.
Why not just stick with the redirect then?
Because it adds an unnecessary step. Googlebot must first crawl the old sitemap, receive the 301, and then fetch the new one. It's not catastrophic, but it wastes crawl budget for nothing.
On a large site with multiple sitemaps or complex indexes, multiplying redirects creates noise. It's better to declare the correct URL directly and save requests.
- The 301 redirect works and doesn't break anything on the indexing side
- Submitting the new sitemap directly via Search Console or robots.txt is more efficient
- The robots.txt remains the most universal method for all search engines
- Avoiding unnecessary redirects preserves crawl budget
SEO Expert opinion
Is this recommendation consistent with practices observed in the field?
Absolutely. We regularly observe websites that keep old sitemaps in redirect for months, even years. Google continues to crawl without problems, but the URL still appears as "redirected" in the logs.
What's problematic is when a webmaster thinks the redirect is enough and never updates the official reference. Result: the sitemap remains technically functional, but monitoring tools display alerts and SEO audits systematically flag this as an anomaly.
In which cases does this rule not apply?
If you have multiple sitemaps declared in an XML index, and you redirect the index itself, the sub-sitemaps are not automatically updated. Googlebot will follow the index redirect, but if internal URLs still point to the old addresses, it creates an unnecessary chain of redirects.
Another case: multilingual or multi-domain sites. If each version has its own sitemap and you migrate one without touching the others, you risk having inconsistencies in cross-references. [To verify]: Mueller doesn't specify if this tolerance also applies to video, image, or news sitemaps — we assume it does, but there's no official confirmation.
Do you really need to bother if the redirect works?
Let's be honest: if your site has three pages and a static sitemap, nobody will die because you leave a 301 hanging around. But on an e-commerce site with 50,000 URLs and multiple segmented sitemaps, every inefficiency accumulates.
And then there's the "professional cleanliness" aspect. An SEO audit that detects redirects on the sitemap is a signal that technical management isn't top-notch. It's better to fix it directly and avoid questions.
Practical impact and recommendations
What should you do concretely during a sitemap migration?
First, update your robots.txt file with the new sitemap URL. That's the foundation. Next, log into Search Console and manually submit the new sitemap in the dedicated section.
If the old sitemap is still accessible, set up a temporary 301 redirect so you don't lose bots that might have the old reference cached. But don't stop there: make sure this redirect disappears once the new URL is well crawled.
What mistakes must you absolutely avoid?
Don't let a chain of redirects trail across multiple sitemaps. If you have sitemap_old.xml → sitemap_new.xml → sitemap_final.xml, Google will follow, but it's pure waste.
Another classic mistake: changing the sitemap URL in the CMS without touching robots.txt or GSC. Result: bots can no longer find the sitemap and you're left wondering why indexation is slowing down.
How do you verify that everything is properly in place?
Check your server logs to see if Googlebot is crawling the new sitemap directly or still going through the old one with a 301. If you see requests on the old URL several weeks after migration, it means the update wasn't picked up everywhere.
In Search Console, verify that the new sitemap appears in the list and that there are no processing errors. If the status stays "Pending" too long, resubmitting manually can unblock the situation.
- Update the robots.txt with the new sitemap URL
- Submit the new sitemap in Search Console
- Configure a temporary 301 redirect from the old to the new
- Verify in server logs that Googlebot is crawling the new sitemap properly
- Remove the redirect once the transition is confirmed
- Audit internal sitemaps (XML index, sub-sitemaps) to avoid inconsistencies
