Kentico stops all updates and security fixes for Xperience 13 on December 31, 2026. We rebuild your site in Next.js and move your pages and media into Sanity or Payload so editors keep publishing. Every page that ranks or has links is kept at its address, or redirected if it changes.
Every Xperience 13 site faces the same choice before January 2027: rebuild on Kentico’s newer product, Xperience by Kentico, run unsupported software, or move.
Through 2026 Kentico ships security hotfixes only. From January 1, 2027 it stops all updates, hotfixes, and security fixes for Xperience 13, and running it is at your own risk.
Kentico calls its newer platform, Xperience by Kentico, a new product, not a continuation of Xperience 13. Moving to it means rebuilding much of the site, and every user, editors included, has to create a new password.
Two critical Xperience 13 sign-in flaws were added to the US government’s list (CISA) of actively exploited vulnerabilities in October 2025, and another serious flaw in April 2026. Kentico patched them, but after December 2026 new flaws stay open.
Pages and media move into Sanity or Payload. Page Builder sections are rebuilt as React components that match the live site.
| Item | What happens | How we handle it |
|---|---|---|
| Pages and page types | Moves unchanged | Each page type becomes a content type in Sanity or Payload, with its fields mapped across and your page structure kept. |
| Page Builder widgets and sections | Rebuilt | Rebuilt as React components that editors can arrange in the CMS, matched to the live site on desktop, tablet, and phone. |
| Media libraries and page attachments | Moves unchanged | Files are moved and re-hosted. Old /getmedia/ and /getattachment/ links are redirected to their new addresses. |
| Old page addresses (Former URLs) | Moves, with changes | The old addresses Kentico already redirects are exported and carried over, so old links keep working after Kentico is gone. |
| Forms | Rebuilt | Rebuilt and connected to the same inbox or CRM. We check what past submissions can be exported when we plan your move. |
| Users and passwords | Moves, with changes | Editor accounts are set up in the new CMS. Kentico passwords can’t be moved, so editors set a new password at launch. |
| Contacts and marketing data | Moves, with changes | Kentico’s contact profiles and activity tracking don’t carry into the new CMS, but can be exported or moved to your CRM. We agree which when we plan your move. |
| Custom .NET code | Rebuilt | Rebuilt in Next.js or replaced with a maintained service. We agree on each one with you before work starts. |
Redirects and URLs
Kentico sites carry more old addresses than most teams realize. Each of these needs its own redirect.
Kentico links to files through /getmedia/ and /getattachment/ addresses that contain a long ID. PDFs and images linked from other sites still use them.
Kentico quietly redirects old page addresses after a page is renamed or moved. Those redirects disappear with Kentico unless they’re carried over.
Each language version of a page has its own addresses. They must map to the same structure in Next.js, or each language loses rankings on its own.
Old campaign and landing pages often aren’t in the sitemap. We pull addresses from Search Console, analytics, and backlinks too.
Next.js hands Google each page as finished HTML, so indexing doesn’t hinge on JavaScript.
We choose the CMS with you before work starts, based on who edits the site and where you want it hosted.
A hosted content platform with real-time editing. Strong fit for marketing teams that reuse content across pages.
An open-source CMS that runs inside the Next.js app. Strong fit when you want one codebase and full data ownership.

“From” is the starting price for the kind of site described. Prices depend on your site’s size and setup. You get a quote before any work starts, and we don’t bill by the hour.
No one can promise how Google will rank your site after a move, including us. What we can promise is the work that protects your rankings, done carefully and put in writing.
Ask us about the guaranteeGoogle decides rankings, not us. Even a careful migration can cause some movement while Google recrawls the new site and works out what changed, and it can take a few weeks to settle.
Google also changes how it ranks sites throughout the year. If an update shifts your traffic, that isn’t something any migration team controls. Anyone who guarantees your rankings is promising something they can’t deliver.
We take every precaution we know of, and we stay accountable after launch.
Every page we can find gets a new home. We collect old addresses from your sitemap, Google Search Console, analytics, and links from other sites. Each one gets a destination: the matching page, the closest match, or a removal you’ve agreed to. You see the full list before launch.
Nothing is removed by accident. Pages you choose to retire are removed on purpose. If any other old link stops working after launch, we fix it.
We watch for 90 days. After launch we track which pages Google indexes, any errors it reports, and traffic to the pages we moved, and we send you a report at 30, 60, and 90 days.
If it’s our mistake, we fix it for free. If something we missed or broke causes a problem in those 90 days, we fix it at no cost.
The guarantee covers our work. It doesn’t cover Google algorithm updates, content you change after launch, pages removed at your request, or problems caused by your host, third-party plugins, or other vendors.
If your team relies on Kentico’s built-in personalization, contact scoring, or marketing automation and has .NET developers in house, upgrading to Xperience by Kentico may suit you better. Kentico now offers it as a managed SaaS service too. If nobody on your team would own a codebase, Kentico to WordPress is a cheaper move than a Next.js build.
Ask if you should stay on KenticoCommon questions about moving from Kentico to Next.js. If yours isn’t here, send us your site and ask. You’ll hear back within one business day.
Get a migration quoteYes. The site keeps working, but Kentico stops all updates and security fixes, so any new vulnerability stays open.
The price includes setting up Sanity or Payload with your content types, editor accounts, and live preview, so editors keep publishing without a developer.
We keep URLs identical wherever possible. Every URL that does change gets a one-to-one redirect, including Kentico’s former URLs and /getmedia/ file links.
Lasting losses come from missed redirects and file links, which we map before launch. Expect some movement while Google recrawls. We monitor search for 90 days and fix anything our work caused at no charge. No one can promise rankings, but our guarantee covers our work.
Yes. That’s a separate migration with its own price: Kentico to WordPress, from $7,500.
Most Kentico sites with up to 25 page templates take six to ten weeks.
