✓24/7 US-based support during and after migration
✓40–70% savings on legacy Db2 support costs

Unusable dashboards due to Db2 row-store latency

Standard Db2 engines choke on dense analytics queries, leaving your team waiting minutes for dashboard renders.

Soaring licensing costs for Db2 Warehouse nodes

Scaling legacy warehouse nodes inflates costs unpredictably—our migration eliminates those per-node fees.

Scalability roadblocks blocking modern analytics features

Your customers demand near-real-time insights, but Db2’s architecture adds friction at every growth step.

IBM Db2 → ClickHouse migration — your questions answered

How do you handle primary/foreign key constraints during IBM Db2 to ClickHouse migration?+

We re‑engineer constraints as ClickHouse join strategies and materialized views—preserving data integrity without transactional overhead.

What about Db2’s complex locking mechanisms?+

ClickHouse uses lightweight locks for MERGE operations. We rewrite your transactional SQL patterns to leverage ClickHouse’s MVCC‑like concurrency, avoiding contention.

Can nested subqueries and SQL PL logic be migrated?+

Yes. Our engineers refactor Db2‑specific procedural logic into ClickHouse interpretations (e.g., ARRAY JOIN, lambda functions) achieving equivalent results with sub‑second performance.

What if my vendor renewal lapses before the migration finishes?+

Your legacy Db2 stays under vendor support until the renewal lapses. After that, our third‑party support handles most operational issues—excluding vendor patches—so you can complete the move without panic.

Start Your Db2 to ClickHouse Migration with Confidence

You don’t have to compromise on operational integrity while modernizing analytics. Our senior engineers deliver a fixed‑scope migration with a clear timeline (4–8 months) and predictable budget ($95k–$480k). Post‑migration, keep your ClickHouse cluster tuned with our optimization services—and cut legacy Db2 support costs by 40–70%.
