Difference between redhat linux 7.3 and 9?
 

Dear all :

I am having a server with Redhat linux 7.3 installed. Currently, i am planning to move the 7.3 to redhat linux 9.

But, can anyone tell me whether is advisable to change the version? wat r the advantages of 9 over 7.3? any drawbacks?

And, any impact to my current server (7.3) ? This server is working as DHCP, DNS, Firewall and File server. Because i have to implement it in a limited time and i do not have test pc for me to test such new linux 9, I really need some advices from experienced person out there.

Pls help. Thanks in advance.

Regards,
William Song
