What Does End of Support (EOS) Mean for Db2 11.5?

Once Db2 11.5 reaches EOS:

• IBM will no longer provide defect fixes, patches, or security updates.

• Access to technical support ends, unless you purchase Extended Support or a Service Extension (if offered).

• Running an unsupported Db2 release could expose your business to security vulnerabilities and compliance risks.

Db2 11.5 Editions and Support Timelines

• Db2 11.5 Standard / Advanced / Enterprise Editions → Supported until April 30, 2027.

• Db2 11.5 Base Edition (PID 5737-N20) → Supported until September 30, 2025.

Always check which edition you are running, since the EOS date is not the same for all Db2 11.5 versions.

Recommendations for Db2 Users

• Plan your migration strategy early. Don’t wait until 2027 (or 2025 for Base Edition).

• Upgrade to the latest Db2 release to stay secure and supported.

• Verify your Subscription & Support (S&S) coverage with IBM to ensure you are eligible for updates until EOS.

Key Takeaway

The main Db2 11.5 EOS date is April 30, 2027, but some editions (like the Base Edition) end support much earlier. By knowing these dates and preparing your upgrade path now, you can avoid unnecessary risks and ensure long-term stability for your Db2 environment.
