Hi

Once look at the below link

How to upgrade rhel6 to rhel7 os [ major to major version ]

@rajeshkathar 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 For ex- rhel 5.6 (to) rhel 5.8 Rhel 6.3 (to) rhel 6.5 But NOT from RHEL 5.x to 6.x

Can someone suggest me which version to upgrade 6 OR 7

If you want to upgrade go with rhel6

Currently my production run on version rehl5.7, so which version that you suggest to upgrade.

Form my side i will prefer rhel5, based on my knowledge rhel5 is the most stable version when compared to 6 and 7 although you can go with rhel6.

But up-gradation is not possible, you need fresh installation and later you have to migrate the required conf file from rhel5 to 6
