IBM Db2 11.5 Support: Frequently Asked Questions
Is the IBM Db2 11.5 still supported?
Yes, but IBM support for the IBM Db2 11.5 ends on Apr 30, 2027. You can upgrade on the vendor's schedule, or move to third-party support and keep the release you're on — issues managed, vulnerabilities remediated, compliance maintained.
When is the IBM Db2 11.5 end of service life (EOSL) date?
IBM lists the end of service life for the IBM Db2 11.5 as Apr 30, 2027.
Can I keep using the IBM Db2 11.5 after its EOSL date?
Yes. EOSL means IBM stops issuing patches and support — the software itself keeps running. Third-party support covers it from there: issue management, security vulnerability remediation, and the compliance documentation auditors ask for, for as long as you choose to run it.
How much does third-party support for the IBM Db2 11.5 cost?
Typically 40-70% below the OEM maintenance renewal price. Exact pricing depends on quantity, service level and location. You get an indicative price within 24 hours and a firm quote within 48.
