Upgrading from RHEL 6.6 to 7.x
by mani_mss from LinuxQuestions.org on (#4YD64)
Hello,
I am a newbie to Linux and would like to upgrade my existing OS from rhel 6.6 to rhel 7.x. From all the forum i have read is to do a clean installation and proceed to install data from the backup. My question is if i were to mount an iso of rhel .x on my rhel 6.6 machine and do a yum/rpm upgrade, what may be the outcome? I believe the OS will see that all packages installed need to be upgraded along with the kernel and will perform the migration directly. So why not we do this migration?Am i missing something here?
Thanks!!
