I think it will come when we want to go for license changing say from evaluation to licnesed package. But here what i'm saying is i havent installed MVS edition, But i installed other editions such as server and Enterprise editions. Now How do i get MVS edition installed?
Ok. Then does it overwrite my earlier installations or just add MVS edition to the my existing version? Do i need to take back up of any files before i start installing ? Does the file dsenv get affected with this?
It won't overwrite anything that's not on the installation media (for example jobs). It will "upgrade in place". Always take a backup before upgrading any software.
