AIX 5.3 end-of-service

The EOM date (end of marketing) has been announced for AIX 5.3: 04/11; meaning that AIX 5.3 will no longer be marketed by IBM from April 2011, and that it is now time for customers to start thinking about upgrading to AIX 6.1. The EOS (end of service) date for AIX 5.3 is 04/12, meaning AIX 5.3 will be serviced by IBM until April 2012. After that, IBM will only service AIX 5.3 for an additional fee. The EOL (end of life) date is 04/16, which is the end of life date at April 2016. The final technology level for AIX 5.3 is technology level 12. Some service packs for TL12 will be released though.

IBM has also announced EOM and EOS dates for HACMP 5.4 and PowerHA 5.5, so if you're using any of these versions, you also need to upgrade to PowerHA 6.1:

  • Sep 30, 2010: EOM HACMP 5.4, PowerHA 5.5
  • Sep 30, 2011: EOS HACMP 5.4
  • Sep 30, 2012: EOS HACMP 5.5
