Best Umbraco Update Companies Worth Considering for Your Next Upgrade

Updating Umbraco sounds simple on paper, but anyone who has gone through a real upgrade knows it rarely is. Versions change, dependencies shift, custom code behaves differently, and suddenly what looked like a routine update turns into a careful technical project. This is usually the moment when companies start looking for specialists who deal with Umbraco upgrades every day rather than occasionally. This article brings together a list of Umbraco update companies that focus on helping teams move between versions without breaking what already works. Some focus on complex enterprise migrations, while others emphasize steady long-term maintenance or performance improvements after the update is done. The goal here is not to rank anyone but to provide a clear starting point for understanding who does this work and how their approaches differ depending on project size, legacy complexity, and internal resources.

1. OSKI

At OSKI, the software development team builds and maintains web platforms using modern technologies such as .NET, cloud infrastructure, and frontend frameworks. Projects typically involve long-term product development, with architecture decisions, integrations, and ongoing improvements handled collaboratively rather than as isolated tasks. Within this context, Umbraco serves as part of broader web development efforts, where long-term stability, maintainability, and clean code remain priorities.

In practice, this approach frequently involves dealing with Umbraco updates and version upgrades, as CMS changes are often necessary when systems evolve or infrastructure is modernized. Work on updates normally takes place alongside refactoring, performance optimizations, and alignment with current technical standards. This is particularly important for organizations operating in multiple markets, where websites must stay reliable while continuing to advance technically, and where upgrades form a regular part of continuous development instead of one-time migrations.

Key Highlights:

• Experience working with Umbraco within .NET based environments
• Focus on long-term software maintenance and development continuity
• Work across cloud infrastructure and frontend technologies
• Experience with integrations and custom web solutions

Services:

• Umbraco website development and updates
• CMS upgrades and technical improvements
• Cloud and infrastructure integration

2. Crumpled Dog

Crumpled Dog works as a creative and technical web agency with extensive experience delivering Umbraco projects, including upgrades and migrations between platform versions. Their work combines design, technical development, and planning, which means updates are often handled alongside structural or visual changes to existing websites. In many cases, upgrades are approached as part of a wider review of how a site performs and how it should evolve.

Their work around Umbraco also includes consultancy, support, and technical reviews, which helps organizations understand the impact of upgrades before changes are made. Infrastructure considerations, deployment environments, and long-term maintenance are typically part of the discussion, especially where older installations require careful handling during version transitions.

Key Highlights:

• Experience with Umbraco upgrades and migrations
• Combination of creative and technical project work
• Consultancy and technical review services
• Support and maintenance for existing Umbraco websites

Services:

• Umbraco upgrades and migrations

3. Foremost Media

Foremost Media focuses on migration and upgrade projects for organizations moving to newer versions of Umbraco or transitioning from other content management systems. Their work is structured around planning, execution, testing, and post-migration adjustments, which helps reduce disruption while changes are introduced. The process typically centers on preserving existing content and functionality while modernizing the underlying platform.

Upgrade projects are usually connected to broader improvements that follow the migration itself, such as refining site functionality or adjusting the implementation to better match current requirements. Ongoing support is also part of their work, allowing websites to remain stable after the upgrade is completed and helping teams manage future updates more predictably.

Key Highlights:

• Focus on Umbraco migration and upgrade projects
• Structured planning and testing approach
• Attention to content continuity during transitions
• Ongoing support after migration

Services:

• Umbraco upgrades and migrations

4. Moriyama

Moriyama works as a technical agency focused on Umbraco development, upgrades, and platform maintenance, with work often centered around keeping existing websites stable while moving them to newer versions of the CMS. Their work includes upgrade and migration projects where content, structure, and integrations need to be handled carefully so that websites continue to function as expected during the transition.

Alongside upgrades, their work also covers support and technical reviews that help identify issues before changes are introduced. Their work around Umbraco updates is closely connected to DevOps and hosting environments, particularly where Azure infrastructure and deployment processes influence how upgrades are carried out. In practice, this means updates are not treated as isolated technical tasks but as part of ongoing platform management, where performance, security practices, and long-term maintainability are considered together with the CMS version itself.

Key Highlights:

• Focus on Umbraco upgrades and migrations
• Experience with Azure environments and DevOps workflows
• Ongoing support for multiple Umbraco versions
• Technical health checks and platform reviews

Services:

• Umbraco upgrades and migrations
• Umbraco website development

5. 16i

16i works as a .NET development agency where Umbraco is used as part of broader web and application development projects. Their work includes maintaining existing Umbraco websites, handling upgrades when older versions reach end of life, and migrating websites from other content management systems when platforms no longer meet current requirements.

Upgrade projects are usually connected to improving performance or simplifying long-term maintenance rather than changing the platform itself. Their approach to Umbraco updates often starts with reviewing the current setup and defining a migration plan before development begins. This helps reduce issues that typically appear when older installations have custom features or inherited code from previous teams. Support and maintenance continue after upgrades, allowing websites to evolve gradually instead of requiring large technical changes all at once.

Key Highlights:

• Experience with Umbraco upgrades and migrations
• .NET based development background
• Work with both existing Umbraco sites and CMS migrations
• Ongoing support and maintenance services

Services:

• Umbraco upgrades and migrations
