Problem
Migrating a legacy Perl system to new hosting often breaks dependencies, runtime setup, and critical functions.
Solution
I run a controlled migration: environment audit, code and DB transfer, web stack setup, and compatibility checks.
Result
The system runs predictably on new hosting with a verified checklist of critical functions after cutover.
Timeline
After brief and access handoff, I prepare a phased migration plan with cutover window and post-check validation.
Collaboration Format
You fill a brief on environment and critical flows → I prepare plan → we migrate and verify → confirm final state.

How It Works in Practice
Legacy Perl migration requires precision: moving code is not enough, the business workflow must remain stable after cutover.
When This Is Relevant
- You need to move to a new server with minimal downtime.
- Module and runtime compatibility risks are high.
- You need a clear post-migration verification checklist.
What I Do in the Project
- I baseline current environment and critical runtime points.
- I migrate code, dependencies, and database with compatibility checks.
- I run controlled validation of critical functions after cutover.
What You Receive
- A working system on the new hosting environment.
- Cutover plan and validated post-migration checklist.
- Risk register with practical stabilization recommendations.
If documentation is limited, we start with a technical brief and focused diagnostics to de-risk migration quickly.
