Hello KranthiRachakonda18000676,
There are some major differences between RHEL 6 and RHEL 7, so there is a significant amount of Engineering & QA effort involved in that change, as opposed to just minor updates of RHEL 6 (i.e. RHEL 6.5 to 6.6). However, with that said, RHEL 7 support is indeed on the roadmap for sometime in either Q1 or Q2 of 2017, but that of course is subject to change as it is quite early on still. That timeline is not guaranteed nor committed to by CA Technologies at this time.
Sincerely,
Dustin Dauncey
