Trusted Informix to Db2 Migration by Senior Engineers
Migrating IBM Informix to IBM Db2 is a well-understood project. We assess your environment, convert catalog references and SPL, handle lock-in rule changes, and execute a fixed-scope migration with senior platform
The lowest-cost way off IBM Informix: our migration tooling automates the repetitive work —you pay senior engineers for judgment, not keystrokes.

Lock escalation surprises
Informix uses a simpler lock model; Db2’s row-level locking can cause unexpected deadlocks if not configured properly. We preemptively tune Db2 to match your workload.
Broken system catalog references
Queries and tools referencing Informix system catalogs break after migration. We map every reference to Db2’s catalog structure before you cut over.
Costly 4GL rework
Legacy 4GL reports and SPL procedures must be rewritten for Db2’s SQL PL — a risk if the migration team lacks deep IBM language expertise. Our engineers have done it many times.
IBM Informix → IBM Db2 migration — your questions answered
How do you handle Informix 4GL reports and SPL procedures?+
Our engineers rewrite them into Db2 SQL PL, preserving business logic while optimizing performance. We also handle any legacy 4GL reports and interfaces, converting them to work natively with Db2.
Can you handle Informix-specific system catalog references in my code?+
Yes. We map Informix-specific system catalog references to Db2 equivalents, ensuring queries, tools, and application code continue to work without error.
What about lock escalation differences between Informix and Db2?+
We pre-configure Db2 to match your Informix lock escalation behavior using workload-specific parameters and test thoroughly to prevent deadlocks or performance degradation.
How long does your Informix-to-Db2 migration take, and what does it cost?+
A typical migration takes 3–9 months with 2–3 senior consultants. The budget ranges from $80,000 to $450,000, fixed scope — no surprises.
