Legacy System Modernization pricing.
Legacy modernization pricing depends on how much of the system can be salvaged versus rebuilt, and how much risk is involved in migrating it safely.
What changes the number.
- Size and complexity of the existing codebase
- How much of it can be modernized incrementally versus rebuilt
- Database size, complexity, and required migration approach
- Whether the system needs to stay live during modernization
- Test coverage currently in place, or the lack of it
- Third-party integrations that need to be preserved or replaced
Included
- Technical audit and written findings
- Modernization roadmap and sequencing plan
- Migration or rebuild work itself
- Testing of modernized components
- Documentation and handover
Not included
- Ongoing hosting or infrastructure costs
- Third-party software licenses
- Long-term support after handover, unless separately arranged
Example ranges, not fixed packages.
Focused module modernization
Scoped after consultation
One risky module or service needs replacing, the rest of the system is stable.
Phased incremental migration
Scoped after consultation
The system stays live while pieces are modernized in sequence over months.
Full rebuild
Scoped after consultation
The audit shows the existing codebase isn't worth preserving.
What affects how long it takes.
- Codebase size and how tangled the dependencies are
- Whether the system must remain live throughout
- Availability of anyone with institutional knowledge of the old system
- Data migration complexity
What we need from you.
- Access to the existing codebase and repository history
- Database access or a recent backup for review
- Any documentation that exists, even if outdated
- Contact with whoever currently maintains or understands the system
From conversation to fixed quote.
Initial call
We discuss what's wrong, what's urgent, and what your constraints are.
Codebase and system review
We get read access to assess actual condition, not just what you've been told about it.
Written proposal
You receive a scoped plan with pricing tied to the specific modernization path we recommend.
