Modernization, not automatic rewrite

A legacy PHP codebase running an outdated framework version or unpatched dependencies is a real security and maintainability risk - but the default fix shouldn't automatically be "rewrite everything." A full rewrite carries significant risk of introducing new bugs into working business logic, and often costs far more than incremental modernization. We start by assessing what's actually salvageable versus what genuinely needs replacing.

What we assess and fix

  • Security audit first - outdated dependencies with known vulnerabilities, deprecated PHP functions, and unpatched framework versions get prioritized over cosmetic code quality issues
  • Incremental framework upgrades where feasible - moving through intermediate versions rather than a risky single jump that breaks compatibility across the whole application
  • Refactoring genuinely problematic areas (identified by the audit) rather than rewriting working code that doesn't need to change
  • Test coverage added to critical paths before refactoring them, so changes can be verified rather than hoped to be correct

Our process

1. Security and dependency audit

Identifying actual vulnerabilities and deprecated code, prioritized by real risk rather than a generic "modernize everything" list.

2. Decide: patch, upgrade, or rewrite (per module)

Different parts of a codebase often warrant different treatment - we make this decision module by module, not as one blanket approach for the whole application.

3. Incremental changes with testing

Changes made in stages with verification at each step, rather than one large risky deployment.

4. Documentation of what changed and why

So future maintenance (by your team or anyone else) understands the current state without archaeology.

Pricing

Rs 80,000-400,000 depending on codebase size, how outdated the current stack is, and how much of it needs genuine refactoring versus patching.

Frequently asked questions

Do we need a full rewrite, or can our existing code be salvaged?
Usually salvaged, at least partially - a full rewrite carries real risk of breaking working business logic and typically costs more. We assess module by module rather than defaulting to a rewrite.
What's the biggest risk in an old PHP codebase?
Usually outdated dependencies with known security vulnerabilities and deprecated functions - these get prioritized in our audit over cosmetic code quality concerns.
Will this break our live site during the upgrade?
Changes are made incrementally with testing at each stage specifically to avoid this - a single risky big-bang upgrade is what we're trying to avoid, not what we do.
Do you add automated tests?
Yes, to critical paths before refactoring them, so changes can be verified rather than hoped to be correct.
How do you decide what to prioritize?
Real security risk first, then maintainability issues that are actually costing you time or causing bugs - not a generic modernization checklist applied uniformly.
What does it cost?
Rs 80,000-400,000 depending on codebase size and how much genuine refactoring versus patching is needed.
