12.1.3 move to new servers and change host/domain name
We are moving our EBS environment from RHEL5 to RHEL7 and have already moved our Dev/Test servers.
The current configuration is a db server and an app server and that will remain the same.
When creating my new RHEL7 servers I have referred to guide on the packages needed and sysctl settings etc. (Doc ID 761566.1)
Then my high-level steps are:
- copy RDBMS app tier to new server and run adcfgclone dbTechStack to setup new environment
- run rman to copy the prod database and restore it as say test
- run adcfgclone dbconfig along with a number of other steps to alter the environment as required to reflect a new instance
