Hello,

Can some one pls answer following 2 questions.?

Trying to upgrade Tower from 3.2.5 to 3.4.2.  
Installation fails with error

Preflight check — require new enough ansible

Msg:: “ your current version of Ansible is too old for this version of Ansuble Tower. Please upgrade.”

Question 1: Thought ansible tower uses the ansible core (2.7.8-1)present in the bundle of 3.4 and installs latest.

Question 2: what is the min core version needed for Tower upgrade to 3.4.2

Thank you.!
