// Informatica → Apache Hop

Get off Informatica.
Keep everything
you've built.

Informatica licence costs are significant — and they compound every year. Two of our clients have already moved to Apache Hop, preserving the logic their teams built over years while eliminating the recurring bill. We don't do the migration for you. We audit your environment, map the path, and guide your team through every decision so the migration lands right the first time.

// Engagement type
Migration audit & guided coaching
2 Clients who have migrated from Informatica to Apache Hop
Audit Full environment inventory before any planning begins
Your team Does the migration — with our guidance at every step
Scoped Plan and decision points agreed before you start
// Audit · Roadmap · Coaching · Validation support
// How we work

We make sure your team can migrate.

The people who know your Informatica environment best are already on your team. Our job is to give them the knowledge, the plan, and the confidence to execute the migration without false starts.

01 // Audit
We map your entire environment before you plan a single sprint
Every mapping, session, workflow, connection, and parameter file is inventoried and categorised. You get a clear breakdown of what translates directly to Apache Hop, what needs adaptation, and where the genuine complexity sits — before any migration work starts.
02 // Roadmap
A migration plan your team can actually execute
Based on the audit, we produce a prioritised migration roadmap — which pipelines to move first, where the hard decisions are, and how to sequence the work to minimise risk. Your team knows what they're walking into at every stage.
03 // Coaching
Hands-on guidance as your team does the work
We run structured coaching sessions alongside the migration. When your engineers hit a hard transform, an unusual pattern, or an architectural decision, we work through it with them — not around them.
04 // Validation
A framework for proving the migration worked
We help your team set up parallel validation — migrated pipelines running alongside Informatica, output compared systematically. The cutover decision is made on data, not confidence.
// Component reference

How Informatica concepts map to Apache Hop

Your team will need to know these mappings. This is the reference we work through together during the audit and coaching sessions.

Informatica Apache Hop equivalent
MappingPipeline (.hpl) — the core unit of transformation logic in Hop
SessionRun Pipeline action inside a Hop Workflow — executes a .hpl file with parameters
WorkflowWorkflow (.hwf) — orchestrates pipelines, handles branching, error paths, and scheduling
Source QualifierTableInput (SQL-based) or CsvInput / ExcelInput for file sources — one transform per source, no implicit join at read time
LookupStream Lookup for in-memory joins on smaller datasets; Database Lookup for row-by-row lookups against a table
JoinerMerge Join — note: unlike Informatica's Joiner, Merge Join requires both input streams to be sorted on the join keys beforehand
AggregatorMemoryGroupBy for unsorted input (holds data in memory); GroupBy for pre-sorted input (lower memory footprint)
ExpressionScriptValueMod (JavaScript) for complex logic; Calculator for arithmetic and date operations without scripting
FilterFilterRows — routes rows to a true or false output stream based on a condition
RouterSwitch / Case — routes rows to named output streams by value; equivalent to Informatica's multi-group Router
SorterSortRows — configurable memory limit with disk spill; required upstream of Merge Join and GroupBy
Update StrategyNo direct equivalent — implemented by routing rows through FilterRows and using TableOutput configured for insert or update, or a combination with Upsert
NormalizerNormalize transform — pivots column values into rows
UnionAppend Streams for unordered union; Sorted Merge when row order matters
Sequence GeneratorAdd Sequence transform — generates an auto-incrementing integer per row
Stored ProcedureStored Procedure transform — calls a database stored procedure and maps input/output parameters
Connected TargetTableOutput, CsvOutput, or any output transform connected inline to the pipeline stream
Parameter file / VariablesHop environment config — project-scoped variables defined per environment (dev, test, prod)
Workflow SchedulerPutki scheduler — triggers workflows on cron, event, or dependency; includes monitoring and alerting

The audit tells you what you're actually dealing with.

Informatica environments vary enormously. The only way to plan a migration accurately is to look at yours first. We inventory your environment, surface the hard parts, and hand your team a plan they can execute with confidence.

// What carries over

Your team's expertise doesn't start from zero

Informatica and Apache Hop use different paradigms — Informatica's port-and-link mapping model versus Hop's row-streaming pipeline — but the concepts are close enough that experienced Informatica engineers ramp up fast. The vocabulary changes. The thinking doesn't.

Transformation concepts
Lookups, joiners, aggregators, filters, expressions — all have equivalents in Hop. The concepts translate; the implementation differs in important ways (Merge Join needs sorted input, MemoryGroupBy has memory limits) and that's exactly what the coaching covers.
Database infrastructure
Same sources, same targets, same JDBC connections. Apache Hop connects to everything Informatica connects to. Your data layer stays exactly as it is.
Business logic
The rules, calculations, and data flows your team built over years migrate with the project. We help them translate — not rebuild from scratch.
No new vendor dependency
Apache Hop is open source. You own the pipelines outright. Putki adds production operations on top — but the foundation is yours regardless.

How a guided Informatica migration unfolds

Every environment is different — timelines depend on what the audit surfaces. But the structure is consistent across every engagement we've run.

1
Week 1–2
Environment audit
We inventory your Informatica repository — every mapping, session, workflow, connection, and parameter file. You get a categorised breakdown of what translates directly, what needs adaptation, and where the genuine complexity sits. This is the foundation everything else is built on.
2
Week 2–3
Migration roadmap and kickoff
Based on the audit, we build a prioritised migration plan with your team — which pipelines move first, how work is sequenced, where the decision points are. Your engineers know exactly what they're walking into before they start.
3
Weeks 3+
Coaching through the migration
Your team does the work. We run structured coaching sessions alongside — working through hard transforms, architectural decisions, and anything that doesn't map cleanly. The pace is set by your team's capacity, not a fixed delivery timeline imposed from outside.
4
Final phase
Parallel validation and cutover
We help your team set up parallel validation — migrated pipelines running alongside Informatica, output compared systematically. When the data matches, you cut over. The decision is yours, made on evidence.

The licence cost isn't going down.

Two clients have already made the move. If you're evaluating your options, the audit is the right first step — it costs nothing and gives your team everything they need to plan the migration properly.
