DBConvert Streams vs Qlik Replicate
DBConvert Streams is a focused self-hosted MySQL ↔ PostgreSQL migration and CDC workflow with a built-in IDE.
Qlik Replicate (formerly Attunity Replicate) is a heterogeneous enterprise CDC platform with a click-to-replicate UI and big-data targets.
DBConvert Streams, running
Quick answer
Choose by job
Choose DBConvert Streams if
- The job is MySQL ↔ PostgreSQL migration plus continuous CDC.
- You want self-hosted control without per-source licensing.
- You want migration, validation, CDC, IDE, and federated SQL in one product.
- You want to move real data, compare what landed, monitor the run, then turn on CDC from the same workspace.
Choose Qlik Replicate if
- The source estate includes Oracle, DB2, SAP HANA/ASE, mainframe, or AS/400.
- Targets include Kafka, Snowflake, Databricks, Synapse, or BigQuery at enterprise scale.
- You want a UI-driven enterprise CDC platform without GoldenGate-grade scripting.
- You already run on the Qlik Data Integration stack (Compose, Enterprise Manager).

AI and MCP
The AI difference
DBConvert Streams
DBConvert includes AI and read-only MCP directly in the product used for focused MySQL–PostgreSQL migration, validation, and CDC operations.

Qlik Talend Cloud now has agentic data engineering, specialized agents, AI-generated SQL, and a Qlik MCP server for external assistants.
What to know: These AI and MCP capabilities belong to Qlik Cloud or Qlik Talend Cloud. Current Qlik Replicate documentation remains focused on replication and does not establish them in the Replicate SKU.
Where DBConvert Streams goes further
Skip enterprise procurement entirely
Free IDE tier plus paid migration and CDC runs, no per-source/instance contract, no integration partner. Setup is minutes to hours on desktop or Docker.
Validate with data, not just job metrics
Compare views, row counts, schema diff, and run history ship inside the same workflow — Qlik typically leans on Compose or external tooling for deeper compare.
Keep an IDE and federated SQL in the same product
Daily SQL, ER diagrams, and cross-source queries over MySQL, PostgreSQL, Parquet, CSV, and S3 — capabilities outside Qlik Replicate's scope.
Where Qlik Replicate wins
Replicate from an enterprise-heterogeneous estate
Oracle, SQL Server, DB2 (LUW/zOS/iSeries), SAP HANA and ASE, MongoDB, mainframe (IMS, RMS), and AS/400 as sources — a replication matrix DBConvert Streams does not attempt.
Note — For one-time or scheduled migration across supported relational engines, the broader DBConvert product line offers dedicated conversion and synchronization tools. It is not a replacement for Qlik’s heterogeneous enterprise CDC matrix.
Explore DBConvert migration toolsLand changes in big-data sinks
Kafka, Snowflake, Databricks, Synapse, BigQuery, Redshift, and S3 as targets, with schema/DDL replication configurable on most sources.
Operate enterprise CDC without GoldenGate-grade scripting
The click-to-replicate UI is the product's signature — easier to stand up than script-heavy enterprise CDC, with Compose and Enterprise Manager for modeling and fleet ops.
See it on your own databases — self-hosted, free evaluation, no credit card.
Workflow
Run a MySQL ↔ PostgreSQL migration plus CDC without an enterprise CDC contract
- 1Connect source and target and review the schema diff with type mapping.
- 2Run the full load with resumable checkpoints and parallel writes.
- 3Compare row counts and sample content before cutover.
- 4Continue with log-based CDC and watch throughput and lag in Stream Monitor.
Qlik Replicate is the right answer when the estate is enterprise-heterogeneous with big-data sinks. DBConvert Streams is the right answer for focused MySQL ↔ PostgreSQL work under self-hosted control.
FAQ
Frequently asked questions
Can DBConvert Streams replace Qlik Replicate?
For MySQL ↔ PostgreSQL workflows, yes — and the same product covers migration, validation, and continuous CDC. For Oracle, DB2, SAP HANA/ASE, mainframe, or AS/400 sources, or for big-data sinks (Kafka, Snowflake, Databricks), no — that stays in Qlik Replicate territory.
How does Qlik Replicate compare to Oracle GoldenGate?
They sit in the same heterogeneous-enterprise-CDC market. The common framing: GoldenGate is more powerful and more script-heavy (Extract/Pump/Replicat process model, DBA-grade ops, supports active-active with conflict resolution); Qlik Replicate is more UI-driven and easier to stand up but lacks GoldenGate's deepest active-active features.
Does Qlik Replicate handle migration too, or only CDC?
Both. The "full-load" mode performs the initial migration (with parallelism), then the CDC mode keeps targets aligned via log-based replication. Same shape as DBConvert and most enterprise CDC tools.
How is validation different?
Qlik Replicate provides job monitoring, throughput, lag, and error metrics. Deeper compare-and-validate workflows typically rely on Qlik Compose or external tooling. DBConvert ships compare views, row counts, schema diff, and run history inside the same workflow.
Pricing comparison?
Qlik Replicate is licensed per source/instance under enterprise contract; total cost depends on the source matrix and number of pipelines. DBConvert has a free IDE tier and paid migration and CDC runs without per-source fees. Different procurement brackets — Qlik Replicate sits with enterprise data-integration platforms; DBConvert sits with operator tools.
When does each clearly win?
Qlik Replicate wins when the estate is enterprise-heterogeneous, targets include big-data sinks, and a UI-driven enterprise platform is the requirement. DBConvert wins on focused MySQL ↔ PostgreSQL workflows under self-hosted control, with IDE and federated SQL bundled in.
