IBM AIX 7.3 TL4 Support: Frequently Asked Questions
Is the IBM AIX 7.3 TL4 still supported?
Yes. The IBM AIX 7.3 TL4 is currently supported by IBM, and third-party support is available as an alternative — issue management, vulnerability remediation, and compliance help independent of the vendor contract.
When is the IBM AIX 7.3 TL4 end of service life (EOSL) date?
IBM lists the end of service life for the IBM AIX 7.3 TL4 as Dec 31, 2028.
Can I keep using the IBM AIX 7.3 TL4 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 AIX 7.3 TL4 cost?
Typically 40-70% below the OEM maintenance renewal price. Exact pricing depends on quantity, service level and location — request a quote and we respond within 24 hours.
