Question:

Technology Level support details on AIX platform for Centrify agent

Answer:

1) According to IBM support lifecycle web page http://www-01.ibm.com/support/docview.wss?uid=isg3T1012517, only AIX 7.1 (TL3 or above) and 7.2 (all TLs) are still in support:

Here are the details from the page:
AIX 7.2 Service Pack Support
Release Release Date End of Service Pack Support (EoSPS)
AIX 7.2 TL1 November 2016 30 November 2019 (estimated)
AIX 7.2 TL0 December 2015 31 December 2018 (estimated)

AIX 7.1 Service Pack Support
Release Release Date End of Service Pack Support (EoSPS)
AIX 7.1 TL4 December 2015 31 December 2019 (estimated)
AIX 7.1 TL3 November 2013 30 November 2017
AIX 7.1 TL2 November 2012 30 November 2015
AIX 7.1 TL1 October 2011 31 October 2014
AIX 7.1 TL0 September 2010 30 November 2013

AIX 6.1 Service Pack Support

AIX 6.1 TL2 November 2008 30 November 2010
AIX 6.1 TL1 May 2008 31 May 2010
AIX 6.1 TL0 November 2007 30 November 2009

AIX 5.3 Service Pack Support
Release Release Date End of Service Pack Support (EoSPS)
AIX 5.3 TL12 April 2010 30 April 2012 (End of Service)

2) In our suite release notes supported platform announcement:
AIX 5.3 last support is Suite 2015
AIX 6.1 last support is Suite 2017.1

That means, starting the coming Suite 2017.2 release, we only support AIX 7.1 and 7.2

3) In our logic, here is the TL requirement:
AIX 5.3 requires TL12 or above (only available if customer uses premium support option)
AIX 6.1 requires TL2 or above (starting Suite 2017.2, only available if customer uses premium support option)
AIX 7.1 requires no TL
AIX 7.2 requires no TL

In summary, Centrify do not require more than what IBM supports.
