Our Services

Application Migration Strategy Services in the UK

Ensure that the application and data transfer go smoothly without any downtime or data loss.

  • Application Rehosting

    Orchestrate moving to a new infrastructure without affecting the code or architecture that is already there. As part of an application migration strategy, we offer:

    • Business analysis of an existing infrastructure,
    • Choosing and evaluating vendors,
    • Making a complete plan for migrating old apps to the cloud, data centers, and other places,
    • The process roadmaps, which show important pillars,
    • A “lift and shift” move to new infrastructure with help after the move.

    Save your resources and make your firm more cost-effective for many opportunities.

  • Application Replatforming

    We fine-tune and adapt the legacy application migration strategy and execution, balancing efforts and benefits, to ultimately optimize performance with the help of:

    • Analysis of the current environment, unveiling hidden dependencies and limitations, 
    • Drafting a plan for moving legacy applications (such as moving an on-premise server to the cloud or switching to containerization with Docker),
    • Selection of a target platform or provider, 
    • Minor codebase revision to decrease operational expenses and increase performance, 
    • Ongoing post-replatforming support. 

    Instead of a full rewrite, legacy application replatforming allows you to achieve efficiency and future-readiness through targeted changes.

  • Refactoring an Application

    We rewrite and restructure elements of your program as part of our legacy migration plan, but we don’t change the fundamental functions throughout our legacy application migration strategy. We offer:

    • Analysis of the codebase,
    • Making a plan for moving a legacy system (for example, through modular restructuring, incremental refactoring, branch-based refactoring, etc.),
    • Making unit tests throughout the application migration testing strategy,
    • Refactoring, which includes getting rid of duplicates, renaming things for clarity, and so on,
    • Drafting documents and passing them on.

    You may improve your app’s key features while keeping your business running and performing well by migrating legacy applications.

Our Process

Legacy Application Migration Strategy Workflow

We assist businesses in migrating from restrictive, costly infrastructures to flexible platforms that encourage new ideas. We don't just regard cloud and modern hosting as venues to execute workloads. We see them as the building blocks for change that happens faster and more safely.

01.

01. Analysis

We start exploring, listing current systems, doing static analysis, profiling at runtime, and mapping dependencies between apps, databases, and integrations. Based on these results, we suggest one or more application migration options and weigh the pros and cons. As a result, you get the application migration strategy document with all the findings.

02.

02. Execution

Upon agreement, we set up environments, establish networking and security, and do trial migrations when needed for each application or collection of services. Our engineers break up important systems, identify hidden dependencies, and deal with technical debt that could put the move at risk.

03.

03. Quality Assurance

Testing is an important aspect of our methodology, not something we do at the end. We follow the agreed-upon application migration testing strategy by making or adding to unit, integration, system, performance, and security tests. When coverage is low, we add characterization tests to record how things are working before the move.

04.

04. Deployment

We do the final cutover according to a detailed runbook when everything is ready. CI/CD pipelines, infrastructure as code, feature flags, and safe rollout patterns like blue-green or canary deployments help keep unexpected downtime from happening. After deployment, we monitor performance and error rates, resolve edge cases, and fine-tune capacity and costs.

Our Values

How Do We Make Our Application Migration Strategies in the UK Safe?

01

NDA-Protected

Your privacy is safe from the first workshop until the last handover. We sign NDAs, limit access to sensitive areas, and follow stringent internal rules to make sure that your code, data, and business logic stay safe for the whole project.

02

Quality Centers Inside

Our Business Analysis Office, Project Management Office, and Quality Assurance Office all work together to ensure that every application migration plan stays on track, following the ISO 9001:2015 rules.

03

Approach Based on Value

Your application migration approach should be based on specific business goals, such as lowering infrastructure costs, making the system more resilient, speeding up releases, or making the customer experience better. We focus on situations that provide real benefit instead of just technical wins.

04

Safety

Your desired architecture must include identity management, encryption, network segmentation, backups, disaster recovery, and monitoring. Your systems don't get weaker with each release; they get stronger and easier to audit.

FAQ

Questions and Answers

  • How do you choose the best application migration strategy for us?

    We begin by looking at your current situation, including your architecture, dependencies, SLAs, and business goals. We then look at other tactics for migrating applications, like rehosting, replatforming, and refactoring, and suggest a legacy application migration plan that strikes a compromise between risk, cost, and speed.

  • How can you make sure that moving doesn't create downtime or loss of data?

    The plan includes your application migration testing strategy from the start. Before we cut over, we check each step using dry runs, shadow traffic, data verification, and rollback procedures. Blue-green and canary deployments are two ways to reduce downtime. Automated checks make sure that the data is the same in both the old and new settings before we move users over.

  • What do we actually get with an application migration strategy document?

    You get a real-world application migration strategy document that includes a current-state analysis, a goal architecture, migration waves, dependencies, risks, and KPIs. It also has your plans for testing the migration of your application, the environment, and the cutover runbooks.
