At a glance
| Sources | Oracle, SQL Server, Db2 (LUW, iSeries, z/OS), MySQL, MariaDB, PostgreSQL, Sybase ASE, SAP HANA and SAP apps, Informix, MongoDB, Salesforce, IMS, cloud managed variants |
| Targets | Relational databases, Snowflake, BigQuery, Redshift, Fabric, Synapse, Databricks, Iceberg, Kafka, Kinesis, Pub/Sub, Event Hubs, S3, GCS, ADLS |
| CDC mechanism | Reads the source transaction log (MS-CDC option for SQL Server; SAP extractors and Salesforce streaming CDC for apps) |
| Initial load | Yes, full load followed by change processing in the same task |
| Schema evolution | Metadata changes are captured from the transaction log, per the architecture page; check DDL support per endpoint |
| Latency | Vendor states near real-time; no figures published |
| Conflict handling | Apply Conflicts error policy (duplicate key, zero rows affected); not a multi-master tool |
| Monitoring | Web console task monitoring; Qlik Enterprise Manager is a separate product for many servers |
| Deployment | Client-managed on Windows or Linux, on premises or on a cloud VM |
| Licensing | Commercial, by quote; available endpoints depend on the licence |
Qlik Replicate fits enterprises that need one replication tool across Oracle, SQL Server, Db2 (including z/OS), SAP and cloud warehouses, run on their own Windows or Linux servers. It is quote-only and licensed by endpoint, so confirm that every source and target you need is in your licence before signing.
Overview
Qlik Replicate is the change data capture and replication engine in Qlik's client-managed data integration line. It was previously sold as Attunity Replicate, and the documentation still uses the Attunity name for its legacy ARC mainframe agents. A Replicate task runs a full load of the selected tables, then reads the source transaction log, groups changes by transaction and applies them to the target when each transaction commits. Design and monitoring happen in a web console served by the Replicate server.
The May 2026 support matrix lists the server on Windows Server 2016 to 2025 and on Red Hat Enterprise Linux 8, 9 and 10 or Amazon Linux 2023. Sources include Oracle, SQL Server, Db2 for LUW, iSeries and z/OS, MySQL, PostgreSQL, SAP HANA and SAP application extractors, MongoDB and Salesforce; targets add Snowflake, BigQuery, Redshift, Microsoft Fabric, Databricks, Kafka, Kinesis, Event Hubs and cloud object storage. Qlik's managed alternative is Qlik Talend Cloud, sold separately.
Key features
- Log-based change capture that reads source transaction logs, with transaction-grouped apply on the target
- Full load plus CDC in one task, with changes buffered until the affected tables finish loading
- Wide endpoint support: relational databases, Db2 for z/OS, IMS (new native source in May 2026), SAP application sources, MongoDB and Salesforce
- Targets across warehouses (Snowflake, BigQuery, Redshift, Fabric, Synapse), lakehouses (Databricks Delta, Cloudera Iceberg) and streams (Kafka, Confluent Cloud, Kinesis, Pub/Sub, Event Hubs)
- Configurable error handling, including an Apply Conflicts policy for duplicate keys and updates or deletes that find no row
- Web-based console for designing, running and monitoring tasks, with change processing metrics
- Can feed Qlik Open Lakehouse as a native source (May 2026 release)
Integrations and ecosystem
Pros and cons
Pros
- One of the broadest documented endpoint lists, including Db2 for z/OS, IMS and SAP application sources
- Full load and CDC in a single task with a point-and-click console
- Runs on your own Windows or Linux servers, so data does not pass through a vendor cloud
- Regular release train with clear end-of-life lists for endpoint versions
Cons
- No public pricing; licences are scoped to specific endpoints
- ODBC endpoints are restricted to cases approved by Qlik Professional Services
- Managing many servers centrally needs Qlik Enterprise Manager, a separate product
- Each release retires older endpoint versions (for example MySQL 8.0 and Db2 LUW 11.5 sources in May 2026), so upgrades need planning
Pricing
Qlik publishes no list price for Qlik Replicate. Its data integration pricing page lists only the Qlik Talend Cloud editions (Starter, Standard, Premium, Enterprise), all with a Contact Us button, and says client-managed deployment is sold through sales. The Replicate documentation notes that the endpoints available to you depend on your licence. Expect a quote based on the sources and targets you licence.
Pricing checked on the vendor's official page on 7 November 2026. Prices change; confirm before buying.
Who it is best for
Enterprises replicating from Oracle, SQL Server, Db2 (including mainframe) or SAP into cloud warehouses and Kafka, that want a client-managed, console-driven tool.
Typical use cases
- Feeding Snowflake, Databricks or BigQuery continuously from Oracle and SQL Server systems of record
- Offloading Db2 for z/OS or IMS mainframe data to cloud analytics without custom extract jobs
- Streaming SAP application changes into a warehouse or Kafka
- Low-downtime database migrations using full load followed by CDC
Who should look elsewhere
- Teams that want open source, Kafka-native CDC with no licence cost: see Debezium.
- One-off migrations into AWS, where a managed migration service may be enough: see AWS DMS.
Verdict
Qlik Replicate is a strong candidate when your sources include mainframe Db2, IMS or SAP alongside mainstream databases and you want to run replication on your own servers. Its endpoint breadth is the main draw; the costs are quote-only pricing tied to licensed endpoints and a release cadence that regularly drops older database versions.
Frequently asked questions
Is Qlik Replicate the same as Attunity Replicate?
Yes. Qlik Replicate is the current name of the product previously sold as Attunity Replicate. Some components, such as the legacy Attunity Replicate Connect (ARC) mainframe agents, still carry the old name in the documentation.
How is Qlik Replicate priced?
Qlik does not publish a price. Client-managed products are sold through sales, and the endpoints you can use depend on your licence, so ask for a quote listing every source and target.
What operating systems does Qlik Replicate run on?
The May 2026 support matrix lists 64-bit Windows Server 2016, 2019, 2022 and 2025, and Red Hat Enterprise Linux 8.x, 9.x and 10.x or Amazon Linux 2023.
Is Qlik Replicate the same as Qlik Talend Cloud?
No. Qlik Replicate is client-managed software you install. Qlik Talend Cloud is Qlik's managed integration platform, priced by usage capacity per edition and also sold by quote.
