A Domain Migration and URL Change Checklist: What to Do Before, During and After the Move

Key Takeaways: Identify the Move, Prepare, Launch, Then Watch

A site move (changing your site's address or where it's hosted) has a lot of moving parts, and something always tries to slip through. After working through Google's site-move guides and the Search Console Help pages, here's what I'd want every beginner to know.

1. First, figure out whether your URLs change — A new domain, an HTTPS switch or a new URL structure all change URLs. Switching servers or hosts only doesn't. Google has a separate guide for each
2. Preparation centers on an old-to-new URL map — List every old URL and pair it with its new URL. Google treats this mapping as the core of the move
3. Launch day is redirects, unblocking, Change of Address and sitemaps — Turn on 301 redirects, remove staging noindex and robots.txt blocks, and use Search Console's Change of Address tool only if the domain changed
4. Keep redirects for at least a year, and keep paying for the old domain — Google recommends keeping redirects as long as possible, generally at least a year, and renewing the old domain for at least a year

Let's walk through identifying your move, then the prep, launch-day and post-move checklists, and finally the mistakes I see most.

1. Start by Identifying What Kind of Move You're Making

"Site migration" covers several different jobs. Which one you're doing decides your to-do list.

The Change of Address tool lives in Search Console (Google's free tool for checking how your site appears in search). It tells Google "this domain has moved over there." The Help page says not to use it for HTTP-to-HTTPS, moving pages within your site, www vs. non-www, or moves without visible URL changes.

The mix-up I run into most often is someone hunting for the Change of Address tool for an HTTPS switch. Sorting out the type first saves a lot of wasted effort.

This article uses a domain change, the move with the most steps, as the running example. Apart from the Change of Address tool, the steps are nearly the same for the other URL-changing moves.

2. Pre-Move Checklist

Most moves are won or lost in preparation. Here's what beginners need, based on Google's site-move guide.

Prepare the new site

• Build the new site and test every page, image, form and PDF on a staging environment
• Add noindex (the "don't show in search" instruction) to staging, and keep a list of where you added it
• Set up HTTPS (encrypted connections)
• Make sure the new robots.txt (the file that tells crawlers where not to go) only blocks what it should
• Verify both old and new sites in Search Console, including www/non-www and HTTP/HTTPS variants
• Install analytics so you can track usage on both the old and new sites
• Confirm your server can handle extra load, since Google crawls more heavily right after a move

Bought a used domain?

If the new domain was previously owned, check Search Console for manual actions (penalties for spam and similar) left over from the previous owner. Google's guide includes this in its prep list.

Build the old-to-new URL map

This is the heart of the prep.

1. Collect your old URLs — Google suggests starting with your most important URLs and using sitemaps, server logs, analytics and Search Console's Links report
2. Include images, PDFs and videos — They may get image search traffic and inbound links
3. Pair each old URL with a new URL — A spreadsheet with "old URL" and "new URL" columns is enough
4. Decide what happens to URLs with no match — Merged pages should 301-redirect to the page they were merged into. Only removed pages with no equivalent replacement should return a 404 or 410 (both mean "not found") on the new site

When you actually build the map, you'll be surprised how many old URLs turn up in analytics and link reports that never appeared in your CMS. I don't consider a map "done" if it came only from the CMS page list.

Pick your timing and scope

Google suggests moving during a slower traffic period, accounting for seasonal patterns. For large sites, it describes moving one section first, measuring the effect, then moving the rest. And keep other big projects, like a redesign, on a different schedule. Google recommends changing one thing at a time.

Finally, record rankings for your key keywords and traffic by page. Without a baseline, you won't be able to judge what happened after the move.

3. Launch-Day Checklist

With prep done, here's launch day, following the order in Google's "Start the site move" steps.

1. Turn on 301 redirects — Permanently redirect each old URL to its matching new URL. Point straight at the final URL, with no chains
2. Remove staging noindex and robots.txt blocks — Work through your list and clear every one
3. Check canonicals — Each new page's canonical (the "main version" label) should point to its own new URL
4. Test the redirects — Spot-check key URLs with Search Console's URL Inspection tool, and use a crawler for bulk checks
5. If the domain changed, submit a Change of Address — Do it for every verified variant of the old domain (www, non-www and so on), including ones you don't use
6. Submit the new sitemap — The sitemap is the file listing your pages for Google

What the Change of Address tool actually does

According to Search Console Help, for 180 days after you submit, Google prioritizes crawling and indexing the new site and favors it when choosing canonical pages. Both properties show a notice that the move is in progress during that time.

Before submitting, the tool runs a quick check to confirm you own both sites and that a few pages have 301 redirects. If a critical check fails, you have to fix it before continuing. Help recommends setting up a 301 from the old homepage (and ideally your main pages) to the new site as preparation.

For 301 basics and setup, see "What Is a 301 Redirect?"

4. Post-Move Checklist

Flipping on redirects isn't the finish line. The next few weeks are the actual move.

Update links to the new URLs

• Rewrite internal links (navigation, in-article links) to the new URLs
• Ask sites linking to your old URLs to update them, starting with the links that send the most traffic
• Update social profiles, ad landing pages, and printed materials like business cards

Google's guide notes that redirects slow things down, so internal links and as many inbound links as possible should point at the new URLs.

Watch the numbers shift

Google's guide notes that the old sitemap may show redirect warnings during a move. That's expected and can be ignored.

How long until it settles?

Google says temporary ranking fluctuation during a move is normal. Even medium-sized sites can take a few weeks or more before new URLs gradually appear, and larger sites take longer.

What I take from that: don't judge the move after one week. It happens URL by URL, so don't panic over a partial picture.

5. Moving Hosts Without Changing URLs

New server or hosting provider, same URLs? Follow Google's "Changing your web hosting" guide instead. No redirects, no Change of Address tool.

1. Copy the site to the new host and test it (if you use a temporary hostname, add noindex)
2. At least a week before the move, lower your DNS TTL (how long the internet caches where your domain points) to a few hours so the switch spreads faster
3. Make sure firewalls and DoS protection aren't blocking Googlebot (Google's crawler)
4. Remove staging blocks and point DNS at the new host
5. Shut down the old host only after its traffic reaches zero

Google's guide says it's normal to see a temporary drop in Googlebot's crawl rate right after the switch, followed by a steady increase over the next few days.

6. How Long to Keep Redirects and the Old Domain

"When can we turn the old stuff off?" comes up in every move. Here's what Google's documentation says.

What I found interesting reading these side by side is that "1 year," "180 days" and "consider indefinitely" each serve a different purpose. After 180 days, Help says Google no longer recognizes any relationship between the old and new sites and treats the old one as unrelated. And if the old domain lapses and someone else registers it, every link and redirect pointing there is out of your hands.

7. Common Misconceptions and Mistakes

Here are the misunderstandings and missteps I hear about most. For redesign-specific mistakes, see "5 Website Redesign Mistakes That Wipe Out Search Traffic."

Misconception 1: "301 redirects leak ranking value"

Google's site-move guide says 301 and other permanent redirects don't cause a loss in PageRank (the value passed through links). Honestly, skipping redirects out of fear costs far more.

Misconception 2: "Use the Change of Address tool for HTTPS"

Don't. The tool is for domain and subdomain changes. HTTPS switches are handled with 301 redirects and an updated sitemap.

Mistake 1: Moving again right after a move

A moves to B, then B moves to C soon after. Search Console Help says not to chain site moves, and that you can't immediately submit another change of address from B to C.

Mistake 2: Merging several sites into one at the same time

Help recommends not combining multiple moves into a single destination at once. Move one site, let traffic stabilize, then move the next.

Mistake 3: Letting the old domain lapse once the move "looks done"

Redirects only work while the old domain still resolves. Drop it and every old link and bookmark becomes a dead end.

8. How to Check Your Own Site

The hard part of building a URL map is deciding which URLs to verify first. Start with pages that actually bring in search traffic. LinkSurge's ranked keywords analysis lists the keywords and pages a domain ranks for, so running it on the old domain before the move makes prioritizing easier.

To compare rankings before and after, start recording a few weeks ahead. LinkSurge's rank tracker records your keyword rankings automatically every day.

To check settings template by template after the move, the AI Ready check reviews robots.txt and canonical settings item by item. New to Search Console? Start with "Your First Hour in Google Search Console."

Quick Check

Q1: Do you use the Change of Address tool when switching from HTTP to HTTPS?

Answer: No. The tool is for domain and subdomain changes. HTTPS switches are handled with 301 redirects and an updated sitemap.

Q2: How long does Google prioritize the new site after a Change of Address request?

Answer: 180 days. During that window Google prioritizes crawling and indexing the new site. Keep redirects at least 180 days, longer if they still get search traffic.

Q3: When moving hosts without changing URLs, when can you shut down the old server?

Answer: Once traffic to the old host reaches zero. That's the point at which Google's guide says you can shut it down.

Frequently Asked Questions

Will a domain migration hurt my rankings?

Google says temporary ranking fluctuation during a move is normal, and even medium-sized sites can take a few weeks or more before new URLs appear. If redirects are correct and staging blocks are removed, things typically settle over time.

When can I remove the old redirects?

Google recommends keeping them as long as possible, generally at least a year. If you used the Change of Address tool, keep them at least 180 days, longer if they still get Google Search traffic. Other sites' links and readers' bookmarks are another reason to keep them long-term.

Can I redesign and migrate at the same time?

It's not recommended. Google advises changing one thing at a time, and Search Console Help warns that combining a move with a content and URL-structure redesign is likely to reduce traffic.

Anything special to check when moving to a used domain?

Check Search Console for manual actions left over from the previous owner. If any remain, fix the underlying issue and request reconsideration.

Conclusion: Build the Map and the Baseline First, and Move One Thing at a Time

Once you decide to move, build the old-to-new URL map and start recording rankings and traffic before touching anything. On launch day, work through redirects, unblocking, Change of Address and sitemaps in order. Then spend the following weeks watching old numbers hand off to new ones. Keep redirects and the old domain for at least a year.
