Find the Right Cloud for Your AS400
AS400 and IBM i workloads require IBM Power infrastructure, so the migration path differs across cloud platforms. We assess your environment and recommend the right destination based on compatibility, performance, integrations, and your wider cloud strategy.

AS400 Migration Paths
We Help You Choose the Right AS400 Cloud Migration Approach
Not every AS400 (iSeries) environment needs a full rebuild. We help you choose the right AS400 cloud migration path based on what you want to preserve, what needs to change, and how quickly you need to move.
Rehost
Move your existing IBM i environment to the cloud with minimal change, keeping the LPAR, RPG code, CL programs, green screens, and Db2 files intact while moving off physical Power hardware.
Replatform
Keep IBM i for core transaction processing while moving selected workloads, such as reporting, batch jobs, and archival data, to cloud services.
Re-engineer
Modernize IBM i applications by restructuring them into services, rebuilding the interface layer, and preserving the business logic your operations depend on.

How your AS400 cloud migration journey looks with us
We help you map your pathway to a successful AS400 migration to cloud before discussing scope or cost.
01
We look at what you run today
Your system version, how big it is, how you back it up, and which other vendors' software sits on it.
02
We map everything that connects to it
Every system that sends data in or pulls data out, plus your current safety net if something fails.
03
We match it to platforms that can actually run it
Only some clouds run IBM i at all. We narrow it to the ones that fit your setup.
04
We recommend a path and a timeline
Move the system as it is, move it and split off some of the work, or rebuild parts of it. An IBM i architect walks you through what we found.
AI-Assisted Discovery
Explore AI for AS400
We Use AI to Map Your Environment Faster
We use generative AI to read your RPG, trace what connects to what, and turn decades of undocumented logic into a plan you can act on.
01
Code understanding
AI maps your RPG modules, copybooks, and service programs, then explains the embedded business rules in plain language. It generates the documentation rather than rebuilding it from memory.
02
Dependency mapping
AI traces interfaces from the code itself rather than from institutional memory, so the connections nobody documented surface before cutover instead of after.
03
Wave sequencing
AI prioritizes workloads by complexity, risk, and business value, so your migration order is a decision rather than a guess.
04
Parity validation
AI generates test scenarios from your historical job logs and compares migrated output against your existing IBM i results.
