Upgrading Umbraco isn’t just a version jump, it’s often a reset button on how your site actually works day to day. The challenge is finding the right partner who treats migration as more than moving content from A to B. Some teams lean into design refreshes, others focus on performance tuning, while a few handle the whole cycle from planning through long-term upkeep.

In this guide, we’ll take a look at companies that have made Umbraco migration their craft. These aren’t just agencies with a passing familiarity with the CMS, but teams who’ve been through enough upgrades and rebuilds to know where the snags usually happen, and how to get you running smoothly without unnecessary clutter.

1. Oski Solutions

At Oski Solutions, we spend a lot of time working on sites that use Umbraco. For us, migrations aren’t just about moving content from one version to another and calling it done. They’re usually a chance to clean up what’s been hanging around for too long, get rid of unnecessary clutter, and set things up so the CMS actually works for the people using it day to day. We’ve been through enough upgrades to know where the usual headaches are, and we try to deal with those before they become problems.

We also help out beyond the migration itself. Sometimes that means redesigning parts of a site, fixing old integrations, or making sure teams have the support they need after launch. We don’t see the handover as the end of the job. Our role is more about making sure the site can keep running smoothly without requiring constant outside intervention.

Key Highlights:

• Focus on Umbraco migrations and upgrades
• Approach migrations as clean-up and rebuild opportunities
• Work closely with teams to make the CMS usable
• Handle both design and technical aspects of projects
• Stick around for ongoing support when needed

Services:

• Umbraco migration and upgrades
• Custom web development
• System integrations
• Website design and UX improvements
• Hosting and maintenance
• Long-term site support

2. 16i

16i is a UK-based digital agency that tends to focus on practical web solutions rather than overcomplicating things. They work with Umbraco quite a bit, helping companies move sites over, upgrade older builds, or put together something new that teams can actually manage long term. Their approach leans on straightforward development with attention to how the end product will be used, not just how it looks in a demo.

Outside of migrations, they handle broader digital projects too. That includes custom builds, integrations, and ongoing support once the initial job is done. They’ve worked with a mix of sectors, so they’re used to dealing with different requirements instead of trying to force everything into the same template.

Key Highlights:

• UK-based digital development agency
• Strong background with Umbraco CMS
• Focus on practical builds and long-term usability
• Experience across a range of sectors
• Offers both project-based and ongoing support

3. Vsourz

Vsourz is one of those agencies that covers a lot of ground in digital development. They’ve been around long enough to have their hands in plenty of areas, but when it comes to Umbraco, their role is usually tied to migrations, upgrades, and keeping sites manageable after the initial build. They’re not the kind of team that just drops in a CMS and leaves; they tend to stick around for the ongoing stuff like tweaks, updates, and fixes.

Alongside Umbraco work, they handle a wide range of projects from e-commerce to mobile apps, which means they’re used to balancing different priorities depending on what the client actually needs. Their setup feels more like a group that adapts to each job instead of forcing every project into the same mold, which makes sense for companies juggling a mix of platforms and goals.

Key Highlights:

• Experience with Umbraco migrations and upgrades
• Covers a broad range of digital development areas
• Works across web, mobile, and e-commerce projects
• Focus on practical delivery and ongoing support
• Teams spread across different regions

4. Crumpled Dog 

Crumpled Dog is a London-based agency that spends a lot of time working with Umbraco. They’re known for handling migrations, upgrades, and general upkeep, but their work isn’t just limited to the technical side. They also bring design into the mix, which means projects often involve refreshing how a site looks as well as how it runs. It’s a blend of creative and technical that suits teams who don’t want to split those jobs across multiple companies.

They’ve been working with Umbraco long enough to take on the official Gold Partner badge, which basically just signals they’ve done a fair bit with the platform. Beyond Umbraco, they pick up projects in branding, strategy, and design, so clients that come in for a migration can usually stick around for broader support if they need it.

Key Highlights:

• London-based agency with a strong Umbraco focus
• Handles both design and development in-house
• Official Umbraco Gold Partner
• Mix of technical migration and creative work
• Works with branding and digital strategy as well as CMS

5. GrowCreate

GrowCreate is a UK agency that has carved out a steady role working with Umbraco. Most of their projects involve building or migrating sites on the CMS, then keeping them running smoothly with ongoing support. They’ve worked with different industries over the years, so they’re used to adapting the platform to fit specific business needs instead of forcing a one-size-fits-all approach.

They don’t just handle the technical side of Umbraco, though. Their team often gets involved in design and strategy, making sure websites are not only functional but also align with broader goals. For companies that want a long-term partner who can handle both the migration work and the everyday upkeep, GrowCreate tends to fill that gap.

Key Highlights:

• UK-based Umbraco-focused agency

6. CTI Digital 

CTI Digital is a Manchester-based agency that works across a wide mix of digital projects. They’ve been around long enough to build up experience with different platforms, and Umbraco is one of the CMS tools they often use. Their role usually covers migrations, upgrades, and keeping sites running smoothly once they’re live. Instead of just dropping in for the setup, they tend to stick with clients through the longer-term work too.

Alongside Umbraco, they handle a wide spread of services including design, strategy, and marketing. That means teams looking for a single point of contact for both the technical side and the bigger-picture planning can find it in one place. They work with a range of industries, so they’re used to adapting the CMS to suit very different needs depending on the project.

Key Highlights:

• Manchester-based digital agency

• Works across design, development, and strategy

• Provides both one-off projects and ongoing collaboration

7. Foremost Media

Foremost Media is a US-based agency that works on a wide mix of digital projects, with Umbraco being one of the CMS platforms they regularly handle. Their role often includes moving older sites over to Umbraco, upgrading existing builds, or setting up new projects that need a more flexible backend. They also tend to stick around after launch, covering the ongoing support side so businesses aren’t left scrambling when updates or fixes come up.

Beyond the CMS work, they do a fair amount with design, e-commerce, and custom development. That gives them room to adapt depending on whether a project is purely technical or involves more creative planning. They’ve worked with companies in different industries, which shows in how they adjust their approach depending on the size and setup of each job.

8. Scandia 

Scandia is a company that takes on digital projects with a focus on usability and long-term upkeep.

Their approach is practical, usually tied to making sure the final site is something clients can manage without constant outside help.

They also cover broader areas like design, integrations, and support, which means they’re not just dropping in for the one-off migration jobs. Over the years they’ve picked up experience with clients in different sectors, so they’re used to adjusting their methods depending on the size and shape of the project. It’s less about chasing shiny trends and more about putting together websites that actually work day to day.

9. Simon Antony 

Simon Antony is a UK-based agency that has worked with Umbraco for a long time. They usually get involved when companies need to move an existing site over, clean up older versions, or build something new on the CMS. Their approach is practical, focusing on making sure the sites they deliver are stable and manageable once they’re handed over.

They also deal with custom development, integrations, and support, so clients often stay with them beyond the initial project. Since they’ve worked with businesses of different sizes, they’re used to tailoring their process instead of applying the same setup every time. It’s the kind of operation that balances the technical side of things with keeping day-to-day use straightforward.

10. UMB Digital

UMB Digital is a UK agency that has chosen to focus pretty much entirely on Umbraco. That means most of their work involves migrations, upgrades, and custom builds on the platform. They’re not trying to cover every CMS out there, which makes sense for clients who want a team that knows the ins and outs of one system instead of spreading thin across many.

They also handle ongoing support and training, so the handover isn’t just a “here’s your site, good luck.” Because they’re so focused on Umbraco, they’ve been involved in projects of all sizes, from smaller business sites to larger builds with more moving parts. The common thread is keeping things practical and making sure the CMS actually works day to day.

Key Highlights:

• UK-based agency focused mainly on Umbraco
• Handles migrations, upgrades, and custom builds
• Offers training and long-term support
• Works with projects ranging from small to large scale
• Keeps delivery practical and straightforward

11. Oblongata

Oblongata is a small UK-based agency that mixes design with development, often leaning on Umbraco when it comes to CMS projects. They usually take on migrations, new builds, and upgrades, but what stands out is that they also care a lot about how things look and feel for the end user. Their projects don’t stop at the backend setup; design and usability are a big part of the package.

Because they’re a smaller team, their work feels more hands-on compared to bigger agencies. They often stay involved past the initial delivery, covering support, maintenance, and the inevitable tweaks that come up after launch. They’ve got experience across different industries, which shows in how they adapt their approach depending on the type of client and the scope of the project.

Key Highlights:

• UK-based digital agency with a focus on Umbraco
• Handles migrations, upgrades, and fresh builds

12. Mentor Digital 

Mentor Digital is a Bristol-based agency that mixes technical builds with creative design work. A good chunk of their projects involve Umbraco, whether that’s moving older sites over, upgrading outdated versions, or starting fresh with a new build. They tend to cover both sides of the process: the behind-the-scenes development and the user-facing design. That makes sense for companies that don’t want to juggle multiple suppliers just to get one site working properly.

Outside of Umbraco, they do quite a bit in areas like video production, branding, and UX, so their projects often go beyond the usual CMS setup. Clients who come to them for a migration might end up sticking around for strategy, creative work, or long-term support. They’re the kind of team that can handle the technical jobs but also care about how the final product looks and feels.

Key Highlights:

• Bristol-based digital agency
• Regularly works with Umbraco migrations and upgrades
• Covers both design and development in one place
• Involved in branding, video, and creative projects
• Provides long-term support alongside initial builds

13. Mawazo

Mawazo is a Canada-based agency that mixes creative design with technical web development. They use Umbraco as one of their go-to platforms, often stepping in when businesses need a migration, an upgrade, or a full site build. Their projects usually tie together usability and design, so it’s not just about moving content over but also about shaping how the site works and feels.

They don’t just disappear after launch either. Mawazo tends to stay involved with ongoing support, whether that’s small updates, maintenance, or bigger changes down the line. Since they’ve worked with a variety of clients, they’ve picked up the habit of adjusting their approach to fit what each project actually needs instead of pushing a single way of doing things.

14. CMS-Development

CMS-Development is a company that, as the name suggests, spends most of its time working with content management systems.

Their focus tends to be on getting the technical foundation right so websites can be managed without constant outside help.

They also handle related development work like integrations and custom builds, which means clients often come to them for more than just the migration itself. Since they’ve worked across different industries, they’re used to tailoring projects to match specific business needs rather than forcing the same setup on everyone.

They also cover areas beyond Umbraco, like app development, integrations, and branding. That means clients can stick with them for more than just the CMS piece if needed.

Conclusion

When it comes to Umbraco migrations, there isn’t just one type of company doing the work. Some teams keep things very technical, focusing purely on upgrades and fixes, while others mix in design, strategy, and long-term support. The variety is actually useful because it means businesses can pick the setup that fits how they want to work, rather than being forced into a single approach.

If you’re planning a move, starting small can be a good way to test the waters. Even a simple upgrade gives you a feel for how a team communicates and handles problems. From there, it’s easier to decide who’s worth sticking with for the bigger jobs.
