If your company's website was built in Divi over the past several years, there's a good chance it's still running Divi 4. The website may be working perfectly well today, which makes it reasonable to ask why moving to Divi 5 needs to be on your radar at all.
The answer isn't that your Divi 4 website is suddenly going to stop working. Divi 5 officially launched in February 2026, and Elegant Themes has said Divi 4 will continue to receive full support for at least 12 months following that release.
But Divi 5 is now the current development platform, and that's an important distinction. New features and performance improvements are being developed for Divi 5, while Divi 4 has entered the later stage of its lifecycle.
For businesses with established Divi websites, this isn't something we'd recommend ignoring until support becomes an urgent issue. It's something we'd recommend evaluating now.
Do You Need to Migrate a Divi 4 Website to Divi 5?
The quick answer: Yes, eventually. Divi 4 websites do not need to be migrated immediately, but Divi 4 is not a permanent development path. Existing websites should be evaluated for Divi 5 compatibility, including third-party modules, plugins, custom code and Theme Builder templates, so the migration can be planned and tested before it becomes necessary.
This is one of those times when planning ahead really matters. Major platform changes are much easier when they happen on your schedule instead of someone else's.
We've been building websites long enough to know that major platform changes are much easier when they happen on your schedule instead of someone else's.
Divi 4 Isn't Disappearing Overnight
There is no reason to panic if your website is currently running Divi 4. Elegant Themes has built backward compatibility into Divi 5 specifically because it knows existing websites can be complicated.
Divi 5 includes a Migrator that scans an existing website and identifies content that can be converted to the new framework. Supported Divi modules can be converted to Divi 5's new format, while unsupported legacy modules can continue running through Divi 5's backward compatibility system.
That makes the transition considerably more manageable, but backward compatibility shouldn't be confused with a long-term development strategy.
If a page contains an unsupported legacy module, Divi 5 may still need to load the Divi 4 framework to support it. The page can continue to work, but it won't receive the full performance benefits of the new Divi 5 framework.
Backward compatibility gives businesses time to make the transition properly. We think that's exactly how it should be used.
A Divi 5 Migration Should Start With an Assessment
One of the biggest mistakes a business can make is assuming a Divi 4 to Divi 5 migration is simply another WordPress update.
For a relatively straightforward website using standard Divi modules, the process may be simple. For a website that's been running for six or eight years, the story can be very different.
Over time, websites accumulate things. Third-party Divi modules get added. Plugins solve problems that existed three redesigns ago. Custom CSS grows. Child themes contain modifications nobody quite remembers. Theme Builder templates evolve, and functionality gets added by different developers at different points in the life of the site.
Before migrating, we want to know what's actually there.
Divi 5's Migrator can scan pages, posts, Theme Builder templates, Divi Library items, WooCommerce products and other areas of the site for compatibility issues. That's useful information, but it's only one part of a proper website assessment.
We also want to understand which plugins are still necessary, whether third-party Divi modules have Divi 5-compatible versions, where custom code is being used and whether anything on the existing site should be rebuilt differently now that Divi 5 provides a better native option.
Sometimes migration is straightforward. Sometimes it exposes a good opportunity to clean house.
This Is Why We Test on Staging First
We wouldn't recommend running a major migration directly on a live business website and waiting to see what happens.
Neither does Elegant Themes.
A Divi 4 website should be backed up and copied to a staging environment before migration. That gives us a controlled place to run the Divi 5 Migrator, identify compatibility issues and test the website without affecting what customers, employees or search engines are seeing on the live site.
And "the homepage looks okay" isn't enough testing.
Navigation needs to work. Forms need to submit. Responsive layouts need to be checked. Dynamic content needs to populate correctly. WooCommerce functionality needs to work if the website includes ecommerce. Custom functionality, templates, integrations and third-party modules all need to be reviewed.
The more important the website is to the business, the less interested we are in crossing our fingers and clicking Update.
Third-Party Modules Deserve Extra Attention
Divi has a large ecosystem of third-party modules and extensions, and many older Divi websites rely on them.
Divi 5's backward compatibility system means an unsupported legacy module doesn't necessarily prevent a website from moving forward. It can continue to operate using the Divi 4 framework while the rest of the website runs on Divi 5.
That's a useful bridge, but there are tradeoffs. Pages using legacy modules don't receive the full performance improvements of Divi 5, and working with those modules inside the new Visual Builder can be less efficient.
This is where an audit becomes particularly useful. We may find that a third-party module has already been updated for Divi 5. We may find that it can now be replaced by native Divi 5 functionality. Or we may decide that keeping it in backward compatibility mode temporarily is the most practical choice.
The right answer depends on the website.
Waiting Can Turn a Planned Project Into an Urgent One
This is the part businesses should pay attention to.
Divi 4 is still supported, so there is currently time to evaluate, test and plan. That is a much better position to be in than waiting until the website is approaching the end of its supported lifecycle.
Website projects compete with everything else happening inside a business. There are product launches, campaigns, budgets, vacations, holidays and the normal day-to-day work that already fills everyone's calendar. Development teams have schedules too.
If hundreds of businesses wait until the same support deadline is approaching to start evaluating their Divi 4 websites, everyone is trying to solve the same problem at roughly the same time.
We would rather have months to identify an issue than discover it when the migration suddenly needs to happen.
Planning ahead also gives a business choices. You can migrate the existing website as-is, clean up outdated functionality along the way, or decide that the platform transition makes sense as part of a larger redesign.
Those are much better decisions when they're made intentionally.
Migration May Also Be a Good Time to Ask Whether the Website Still Works for the Business
Not every Divi 4 website should automatically be rebuilt.
If the design is current, the content is working, the user experience is solid and the website still supports the business well, a properly tested migration may be exactly what it needs.
But if you're already investing time and money into evaluating a website that was designed six or seven years ago, it's worth asking a larger question: does it still do what you need it to do?
Businesses change. Services change. Audiences change. Content strategies change. Marketing teams ask more from their websites than they did several years ago.
A migration doesn't need to become a redesign, but sometimes it doesn't make sense to carefully preserve a website that everyone already knows needs to change.
That's a business decision, not a Divi decision.
There Are Advantages to Moving Beyond Divi 4
Once an existing website is running natively in Divi 5, the conversation stops being entirely about migration.
The new framework gives us access to the tools we've been using on new website builds: a faster Visual Builder, modern Flexbox and Grid layouts, more sophisticated responsive controls, Design Variables, presets, nested elements and an expanding collection of native modules and functionality.
For an internal marketing team, those improvements can make the website easier to manage and expand. For us as designers and developers, they give us a much better system for building new sections and functionality without constantly working around the limitations of an older framework.
That's ultimately why migration matters. Maintaining compatibility is part of it, but moving to Divi 5 also puts the website back onto the platform where active development is happening.
So, When Should You Migrate From Divi 4 to Divi 5?
There isn't one date that makes sense for every website.
A straightforward Divi 4 site with compatible modules may be ready now. A complicated website with critical third-party functionality may require more preparation. A business already considering a redesign may decide it makes more sense to address both projects together.
If you're running Divi 4, now is a good time to understand what you're working with. Audit the site. Check compatibility. Identify third-party dependencies. Test the migration on staging and find out whether you're looking at a routine update, a cleanup project or something more substantial. Then you can make the decision with actual information and enough time to do it properly.
