Proven Pathways for Your Informix to SQL Server Migration
Migrating from IBM Informix to Microsoft SQL Server is a well-understood project. Our senior engineers use automated pathways to convert schemas, SPL, and data while your legacy system stays live for validation.
The lowest-cost way off IBM Informix: our migration tooling automates the repetitive work —you pay senior engineers for judgment, not keystrokes.
How we support IBM Informix → Microsoft SQL Server after migration
- ✓Side-by-side validation keeps your old system live.
- ✓Senior engineers with deep Informix and SQL Server expertise.
- ✓Fixed-scope projects with predictable timelines and budgets.
- ✓Automated conversion of SPL, tables, and schemas.
- ✓40-70% lower support costs on legacy platform during transition.
- ✓24/7 US-based support for both platforms.
Vanishing Informix Expertise
Qualified IBM Informix DBAs are scarce and expensive, making long-term maintenance unsustainable.
Expiring Hardware Contracts
Your aging Unix/AIX systems carry high hardware maintenance costs that don't support your cloud future.
Complex Code Conversion
Informix SPL, dynamic locking, and 4GL/ESQL applications raise fears of project risk and business disruption.
IBM Informix → Microsoft SQL Server migration — your questions answered
How do you migrate Informix SPL to SQL Server?+
Our automated conversion engine translates Informix SPL into equivalent T-SQL stored procedures. Senior engineers review and optimize the output, and we test it side-by-side with the original on your live legacy system.
Can you migrate Informix tables to SQL Server without downtime?+
Yes. We run the legacy Informix system in parallel with the new SQL Server during validation. Users stay on Informix until we prove the SQL Server environment matches or exceeds performance.
What about Informix dynamic locking and isolation levels?+
Our engineers map Informix's lock modes and isolation levels to SQL Server's locking model. We adjust for differences in transaction handling to ensure data consistency without deadlocks.
How long does a typical Informix to SQL Server migration take?+
A standard migration runs 6-12 months with a team of 2-4 senior consultants. Budgets typically range from $150,000 to $850,000 depending on database size and complexity.
