Red Hat

HI,

is there any way to downgrade my redhat el-5.3 to el-5.2?

thanks...

I dont think so. You could may be compile the kernel for RHEL.5.2 and change your boot configuration. Don't see another way of doing this

There is no clean way of doing it. Basically it requires a fresh install. Why do you need to downgrade? For a particular application?

If you installed your current kernel through rpm or yum, there is a slight chance that the old kernel is being kept in /boot.

I had developed an application, that need to be tested on all possible versions like redhat 5.2, 5.3 centos 5.4, 5.3, suse & all. I have redhat el 5.3 so wanted to just downgrade to 5.2 instead of finding 5.2 DVD.

This would be a GREAT candidate for some sort of virtualization. You can install all the versions into VMs on a platform like VMware or Virtualbox. Your host can run almost any OS and you don't have to find a DVD, you can download the ISO files and use them as though they were the discs.

The general rule of thumb is develop and test on the oldest version of an operating system that you want to support and then test on later versions - not develop on the latest version and test backwards. Most vendors maintain binary compatibility across minor releases of their operating systems and try to maintain backwards compatibility across at least one major release of their operating system.
