Hi,
A beginners starting question...
Our customer is currently running Oracle RAC 10.2 on RHEL 4.7 and would like to "upgrade" to RAC 12 on RHEL 6.
I've read that RHEL major version upgrade is not possible, so this means a new installation, not an upgrade, I suppose.
Given that there is only one schema in the database, rather small, and that the downtime should be minimized,
what would be the best option?
I think the only possible option is to export that schema, do the installation of Linux & RAC, and then import the schema, but maybe there is a better way?
For example, would it be somehow possible to install one cluster member, leaving the first one continue to run,
and then copy the schema over, and make the newly installed the "live" member, while installing the second,
and then finally bringing them together again.
Any document pointers welcome.
Thomas
