3-year cost calculator
Pre-filled for Oracle Database → IBM Db2. Adjust every figure with your own numbers.
Every figure here is an illustrative estimate, not a vendor quote. Defaults are editable starting points compiled from public information; real, binding pricing comes from the vendor or an authorized distributor. See our methodology.
How this is licensed: Oracle and SQL Server license by the vCPUs of the database server VM. Oracle applies a per-core factor and counts ALL vCPUs unless the workload runs on approved hard-partitioned or Oracle-engineered hardware; SQL Server has a 4-vCPU-per-VM minimum. Set $/vCPU to your edition and core factor.
All figures are illustrative and fully editable — adjust the cost-per-vCPU and migration inputs with your own numbers. Not guaranteed vendor pricing (defaults reviewed May 2026). For a binding quote, use the request form below to reach an authorized distributor or partner.
Quick comparison: Oracle Database vs IBM Db2
Common trade-offs teams weigh when staying on Oracle Database versus moving to IBM Db2. These are general, commonly-reported considerations — not statements of fact about any vendor — so check them against your own contract and the vendors' current terms.
- Already in production — no migration effort or risk
- Mature ecosystem with vendor support and SLAs
- Per-core licensing widely regarded as among the most expensive
- Reported audit activity and licensing-compliance exposure
- Hard-partitioning policy can limit virtualization savings
- Steep annual support renewal uplifts are commonly reported
- Ongoing per-core perpetual + support cost to budget for
- Higher vendor lock-in to weigh
- Commercial option with vendor support and SLAs
- Cost model: Per-core (PVU) + support
- Requires a migration (~21 weeks, high effort)
- Per-core (PVU) + support cost
- Higher operational learning curve

Frequently asked
Is migrating from Oracle Database to IBM Db2 worth it?
For most teams facing rising Oracle Database costs, yes — IBM Db2 (per-core (pvu) + support) typically lowers 3-year total cost of ownership, though the right answer depends on workload complexity and in-house skills. Use the calculator to model your own numbers.
How long does a Oracle Database to IBM Db2 migration take?
A typical mid-size estimate is around 21 weeks across six phases — discovery, design, pilot, waved production migration, validation, and decommission. Larger or more complex estates take longer.
