Drupal migration services
Move structured Drupal content into a supported platform or headless setup without losing relationships.
•HEADLESS MIGRATION
Headless CMS Agency
Separate your content from your website design without slowing your team down or losing the traffic you have.
Move to a headless setup only when it will make publishing, design and performance better. Our headless CMS agency plans the content model, builds the front end and checks that every page still works for editors, customers and search.

•Why Suff Digital
A headless build has two sides, and we work on both.
A headless CMS agency has to make the publishing system and the front end work together. We plan the content model with your editors, build around the pages that need to perform, and stay focused on whether the new setup is easier to use after launch.

•Headless CMS services
What Our Headless CMS Migration Services Include
Our headless CMS agency work covers the content model, front-end build, editorial preview, redirects and search checks.
(06)
•A content model your editors approve
Content types, fields and the links between them, built around what your team publishes and signed off before anyone writes code.
•Your existing content, moved field by field
Every field lands somewhere deliberate, links between entries move across as real connections, and anything with no home is named up front.
•Pages that search engines can actually read
A page can be finished before it is sent, built in advance, or assembled in the visitor's browser. Only the first two are reliably read by search engines, so we make that call for each page type based on what has to earn traffic.
•Preview, drafts and scheduling rebuilt
Preview runs through the same code as the live site, and drafts, scheduling and approvals get rebuilt rather than deferred.
•Publishing that behaves predictably
What triggers a rebuild, what clears the cache and how long it takes, written down so publishing is never a matter of hoping.
•Training built around your team's actual work
Documentation and sessions organized around the jobs your team does weekly, not a tour of the system's features.
•What goes wrong
The problems we solve on headless projects
These are the six problems we get called in to fix, and the ones we design out before a headless CMS migration starts.
Diagnose my site •01
The site looks perfect and Google sees an empty page
When the front end is built separately, your text can end up being assembled by the visitor's browser rather than sent by the server. People see a finished page. Search engines can see an empty shell.
02
A better system the team avoids
The new setup is technically superior and your writers avoid it. Preview does not work, the field names mean nothing to them, and publishing now takes a technical request. Output drops within a month and gets written up as a staffing problem.
03
Related content boxes turn up empty
Links between entries, such as an author attached to an article, carry meaning that a flat export cannot hold. They arrive as plain text or vanish, so those boxes go blank and listing pages stop showing the right things.
04
Editors stop trusting the preview
If preview is built through different code from the live site, what a writer approves is not quite what goes out. The small differences add up until the team stops using preview and starts publishing blind.
05
A typo takes half an hour to reach the site
Some setups rebuild every page whenever anything changes. Once you have a few thousand pages, fixing one word means waiting for the whole site to rebuild, so editors start saving up corrections and urgent changes stop being urgent.
06
Images work on some pages and not others
Images usually move to a new home during the project, and the references to them sit in several places: inside articles, in separate fields, and in the data search engines read. Rewrite some and not others and the gaps show up later.
•Headless CMS process
Our Headless CMS Migration Process
(06)
Phase 01
Week 1
We look at what you actually publish
What exists, what goes out each week, and which fields are genuinely used rather than just defined. We also crawl your live site to record every address it serves. The draft content model comes out of that evidence. The weeks against each step are an estimate rather than a final timeline, and the dates we commit to are agreed in your proposal.
Phase 02
Weeks 1-2
Your editors approve the model before it is built
The people who publish work through it with real jobs: write this article, schedule this announcement. Field names, help text and what is required all get settled here, which costs an afternoon instead of a re-import later.
Phase 03
Weeks 2-6
We build the front end against your real content
Pages get built against your actual content rather than placeholder text, so the awkward entries show up during the build. Your existing addresses are treated as a rule the new site follows.
Phase 04
Week 6
We check what the server sends, not what the browser shows
We crawl the new site and compare it with your live one: what arrives before any code runs, page titles, structured data and internal links. Anything that only appears once scripts run gets a decision attached.
Phase 05
Launch day
We point the domain at the new site
The domain switches, caches are warmed in advance, and any redirects go live at the same moment. We then watch error codes and check page speed against thresholds agreed beforehand.
Phase 06
Weeks 7-10
We check the new setup is actually being used
Alongside traffic and search visibility against your old numbers, we look at how often people publish and which fields sit empty. A content model the team avoids starts to rot within a quarter.
•The traffic you already have
Going headless need not change a single web address. What it changes is how your pages are built.
Your addresses can stay exactly as they are, because nothing about separating content from design forces new ones. The exposure is in how pages get built: content once sent complete by the server can end up assembled in the browser instead.
•
Your current address structure becomes a rule the new site follows, not something rediscovered later
•
What the server sends is decided for each page type, against what has to be readable first
•
We crawl the new site and compare it with your live one before the domain switches
•What the move puts at risk
Four headless migration risks, and where we decide each one.
We agree the thresholds before launch and watch them through the switch. If anything crosses one, we point the domain back at the old site, using the rollback we rehearsed beforehand.
•
Search traffic. Content that only appears after scripts run may not be stored, so that is decided per page type
•
How much you publish. A system editors avoid cuts output quickly, which is why they approve the model first
•
Your history. Revision history, scheduling and approval trails rarely move across on their own
•
Everything the old front end did. Forms, search and analytics need a new home before the build
•Headless CMS deliverables
Headless CMS Migration Deliverables
What you receive from a headless CMS agency depends on where your content is coming from, so this starts with your current system rather than with the stack a headless CMS agency would prefer to build.
Month One
Where your content is coming from
✓From WordPress — Post types and custom fields move into the new content model cleanly, and your existing addresses can stay as they are. The work is rebuilding what the theme and plugins were doing: forms, search, memberships and anything else bolted on.
✓From Drupal — The easiest starting point, because the content model is already written down. Types, fields, taxonomies and references translate closely. Views and the editorial workflow get rebuilt rather than moved.
✓From Adobe Experience Manager — Content comes out through the APIs, and the real work is untangling templates and components that assume the front end is attached.
✓From a site builder — Content comes out with some transformation and the design gets rebuilt. Structure is usually implied rather than written down, so the modeling work is larger than the moving work.
Months 2-3
What gets agreed before the build
✓The content model your editors signed — Content types, fields, the links between them and the help text, approved by the people who publish before implementation starts.
✓What each page type has to send complete — The decision for every page type, with what must be readable before any code runs written out.
✓How a content change reaches the live site — What triggers a rebuild, what clears the cache and how long it takes, so publishing is predictable.
Ongoing
Post-launch checks
✓The new site compared with the old one — Page type by page type, covering what the server sends, titles, structured data and internal links.
✓Whether the model is actually being used — How often people publish, which fields sit unused and where workarounds are appearing.

•Frequently asked questions
Common Questions
They fall into three groups. Hosted products built around an API, such as Contentful, Sanity, Prismic and Storyblok. Open source options you run yourself, such as Strapi, Directus and Payload. And traditional systems used headlessly, including WordPress and Drupal through their APIs.
