I want to upgrade RHEL6 to RHEL7 OS [ major to major version ] on test machine. But I not able to find any youtube video or any official document to upgrade. So, anyone have rhel upgrade documents with screenshot or video. Please share.
You can upgrade your current RHEL 6 to RHEL 6.5 I think, but not further due to new systemd addon in RHEL 7. Best solution is install RHEL 7 on new server and migrate data from RHEL 6 to RHEL 7, this is the only way I can suggest now…
I though that by using the Command Line it was possible to go from one to the next?..or am I mistaken?..of course since they’re now using dnf instead of yum it might be impossible, because the old command “yum upgrade” would not or could not possibly get the job done right?..hmm…maybe I’ll actually build a CEntOS box (6.5) and see if I can get to 7.0 using the dnf upgrade command?..interesting…

Till dnf isn’t supported under CentOS 6.5 and you cannot do a upgrade to CentOS 7 directly from CentOS 6.x versions. The only option is to re-install a fresh CentOS 7…
Hi rajesh you can upgrade from one minor release to any other intermediate minor release and up-gradation between major release is not possible, but you can update rhel 6 to rhel 7 by following the guide which was shared by @n_rajeshnadar
OK, I will follow @n_rajeshnadar link. As I observed this web page, This steps is something tedious. I should test this steps on test machine. But, I have to wait until new service pack or new rpm packages will release. So, This is simple and help full to doing up-gradation.
Brand new release of Red Hat Enterprise Linux suite brings some drastic change every system administrator should be aware. However, the product evolution makes it more and more sophisticated or complicated, as you wish. The question is whether those changes are paramount or could be successfully avoided. Here I delivered some manual of how to upgrade from RHEL 6 to 7.
I have tried to upgrade RHEL 6.8 to RHEL7.2. But, If your server is install in GUI [ runlevel 5 ] then server can’t upgrade successful. RHEL only support up-gradation for minimal installation from RHEL 6.8 to RHEL7.2.
