Hello
I need to upgrade from 6.5 to 7.6 and then 7.9
Can I do it ?

Awesome

I tried to upgrade from EL 6.9 to 7.9, but after the rebooting nothing happened. I'm still in EL 6.10 what should I do ?
Due to I tested in the disconnected environment, installed the every single packages which needed to upgrade .

Is there anything like we want to copy everything from old rhel6 server to new rhel7 server? Do we have any tool of this sort? To copy exactly what's there on old server to new?

I'm working on RHEL6 system thats virtualized that i'm attempting this process on, I've gone through all the steps successfully until I got to the install after I mounted the iso when when i ran <redhat-upgrade-tool --iso /media/rhel-7.9 server.x86_64 --cleanup-post> I get an error <redhat-upgrade-tool: not a regular file: /media/> has anyone ran into this issue? so advice would be much appreciated thanks

Will this also migrate application such as splunk or other application?

Yes, well very informational. I'm keeping that in mind, when dealing with my vintage 1950s model installs. If there's additional helpful ideas, please feel free to reply to me here.

It would be greatful if you could tell us the recommended way of server build which supports inplace upgrade for RHEL6,7 and 8
