Urgent Help required

>> Am I able to install (2.3 version) on RHEL 6.10 or RHEL 7.7 versions? 
Will there be any issues? 
>> I know RHEL 6.10 is out of support in November. But I want to 
understand and try in my test environment. 

Why do you ask? If you open te repo link you can see there is 2.3-latest 
there not? Of course you will have issues installing these if you type 
as root cd / && rm -R -f *
You say you are testing, so do the testing.
