We are having issues with the email gateway bastion03. In trying to resolve the issue we have built a bastion01 with RHEL-6 i686 versus RHEL-6 x86_64 and would like to switch over to it
Steps: 1) Copy SSH keys from bastion03 to bastion01 2) Shutdown bastion03 3) Bring up bastion01 with required IP. 4) Test to see if the system core dumps.
If the problem is resolved we are done. If the problem is not, we will move to RHEL-5 to replicate earlier bastion systems.
