The Gradual Transformation: How Alphatec Migrated 500,000 Lines of Code Without Stopping Innovation
The Claims Management Specialists
Alphatec Software Ltd has carved out a distinctive position in the UK software market: they’re the company that makes enterprise-grade claims and incident management accessible to organizations of all sizes. As a small, agile SaaS company, they’ve built ClaimControl—a platform trusted by international brokers, large corporations, local government agencies, and third-party claims handlers across the globe.
Operating across diverse sectors, including housing, logistics, and construction, Alphatec serves everyone from massive international enterprises to small claims handlers. Their secret? Pricing and functionality that scales to meet different organizational needs without sacrificing the robust capabilities that large institutions require.
But Alphatec’s real differentiator isn’t just their software—it’s their pragmatic approach to technology challenges. When they faced one of the most daunting migration projects imaginable, they didn’t panic, didn’t stop innovating, and didn’t accept that small companies can’t tackle significant technical challenges.
The Half-Million Line Challenge
The Scale of the Problem
Most companies would look at migrating 500,000 lines of code from AngularJS to Angular and see an insurmountable obstacle. For a small UK-based team, the math seemed impossible.
The Traditional Migration Playbook:
- Freeze all feature development for 12-18 months
- Dedicate entire development team to migration
- Accept that customers would receive no new features during transition
- Hope nothing breaks catastrophically during the cutover
- Risk losing competitive position while standing still
The Alphatec Reality:
- Small development team that couldn’t be split into parallel tracks
- Customers expecting continuous innovation and new features
- Competitive market requiring ongoing product development
- Limited budget for external resources
- Growing security and compliance requirements from enterprise clients
“We have been using HeroDevs for several years and first worked with them to help us migrate a product with circa 500,000 lines of code from AngularJS to Angular. The size of the project meant that we had to figure out how to run the application with a mix of both Angular and AngularJS without conflicts.” — Alphatec Software
The Hybrid Application Puzzle
The technical challenge went beyond just rewriting code. Alphatec needed to solve a problem that few companies successfully navigate: running a hybrid application that seamlessly combined Angular and AngularJS components without conflicts, instability, or degraded performance.
This wasn’t academic—it was essential to their business survival. Without the ability to migrate incrementally while continuing feature development, they faced a choice between security/modernization and business growth. For a small, agile company competing against larger players, accepting either option meant accepting failure.

The Partnership Model: Embedded Expertise
Beyond Vendor Services: True Collaboration
What set the HeroDevs engagement apart wasn’t just technical capability—it was the collaborative model. Rather than treating migration as a project to be outsourced and forgotten, HeroDevs embedded consultants directly into Alphatec’s development team.
The Xander Factor
HeroDevs consultant Xander became more than just an external expert—he became an integral part of the Alphatec team, working alongside their developers day-to-day. This embedded approach delivered benefits far beyond just completing the migration.
Knowledge Transfer in Action. Every code review, every architectural decision, every problem solved became a teaching moment. Alphatec’s developers didn’t just watch the migration happen—they learned how to execute complex framework transitions.
Contextual Problem Solving. Because Xander worked within the team rather than from the outside, he understood Alphatec’s specific business context, customer requirements, and competitive pressures. Solutions weren’t generic—they were tailored to Alphatec’s reality.
Sustained Capability Building. Long after the migration was completed, Alphatec’s team retained the skills and knowledge to manage their modern Angular application independently.
“HeroDevs provided us with consultants to work as part of our development team to upskill our developers and assist us in migrating to the latest versions of frameworks while still providing that hybrid capability throughout the transition. This expertise helped us massively, and I’m not sure the outcome would have been possible without the assistance of HeroDevs and, in particular, Xander.” — Alphatec Software
The Never-Ending Support Safety Net
While the embedded consulting provided forward momentum, the Never-Ending Support program provided the safety net that made incremental migration viable. Throughout the multi-year journey, Alphatec’s AngularJS components remained secure and compliant, even as they gradually replaced them with Angular code.
This security foundation was critical for several reasons:
- Customer Confidence: Enterprise clients conducting IT security assessments received assurance that even legacy components remained protected.
- Compliance Requirements: Local government and corporate clients required continuous security compliance—the migration timeline couldn’t compromise this.
- Business Development: New customer opportunities couldn’t be declined due to framework security concerns.
- Development Focus: The team could concentrate on migration work rather than firefighting security issues.
“The Never-Ending support program allows us to migrate/update frameworks over time while still developing our product’s features and capabilities. We are not of a size that would allow us to have an entirely separate dev team to build a new version in parallel.” — Alphatec Software
The Small Company Advantage
Redefining What Small Teams Can Achieve
Alphatec’s journey challenges the conventional wisdom about what small software companies can accomplish. The traditional narrative says that massive technical undertakings require massive teams and budgets. Alphatec proved otherwise.
- Strategic Resource Multiplication: Rather than trying to build every capability in-house, Alphatec strategically partnered with HeroDevs to access world-class expertise exactly when and how they needed it.
- Focused Investment: The embedded consultant model meant Alphatec paid for outcomes and knowledge transfer, not just labor hours.
- Capability Retention: Unlike traditional consulting engagements, where knowledge walks out the door when the project ends, Alphatec’s team gains permanent capability that continues to deliver value.
Business Continuity as Competitive Advantage
While competitors might have frozen development for extensive migrations, Alphatec maintained its innovation pace. This continuity became a competitive differentiator:
- Customer Commitment Fulfilled: Existing customers continued receiving new features and improvements throughout the migration.
- Market Responsiveness: Alphatec could respond to market opportunities and customer requests without artificial constraints.
- Revenue Preservation: No need to explain to customers why feature development had stopped or to accept reduced contract values due to development freezes.
- Team Morale: Developers worked on meaningful feature development alongside migration work, rather than grinding through months of pure technical debt.

Lessons for Small Software Companies
The Incremental Migration Playbook
Alphatec’s experience offers a proven playbook for other small software companies facing daunting technical modernization:
- Reject False Choices: Don’t accept the premise that you must choose between innovation and modernization. With the right approach and partners, you can pursue both simultaneously.
- Embrace Hybrid Architectures: Running mixed old/new technology during transition isn’t a compromise—it’s a strategic advantage that enables business continuity.
- Invest in Knowledge Transfer: Choose partners who teach rather than just deliver. The learning your team gains becomes permanent capability.
- Secure the Foundation: Never-Ending Support or similar programs ensure security doesn’t become a crisis while you’re modernizing.
- Maintain Customer Focus: Your customers don’t care about your technical debt. Keep delivering value to them while you fix the foundation.
When to Consider the Alphatec Approach
The Alphatec model works particularly well when:
- Legacy codebase is substantial (hundreds of thousands of lines), making big-bang migration infeasible
- Team size is constrained, preventing parallel development tracks
- Customer expectations require continuous innovation despite technical challenges
- Competitive pressure demands maintaining development velocity
- Budget constraints rule out massive consulting engagements
- Knowledge retention matters more than outsourced execution
The Partnership Selection Criteria
Alphatec’s success wasn’t just about choosing to migrate incrementally—it was about choosing the right partner. Their experience suggests several critical factors:
- Embedded Capability: Look for partners willing to work within your team, not just deliver from the outside.
- Teaching Orientation: Prioritize partners who transfer knowledge rather than hoarding expertise.
- Hybrid Expertise: Ensure partners have proven experience with mixed-framework architectures, not just migrations.
