AIX - BOS Installation Methods

AIX - BOS Installation Methods


AIX - Installation - Migration

AIX - Installation - Migration

This method upgrades from earlier versions of the AIX BOS to AIX 6.1 (see the release notes for restrictions). The migration installation method is used to upgrade from an existing version or release of AIX to a later version or release of AIX. A migration installation preserves most file systems, including the root volume group, logical volumes, and system configuration files. It overwrites the /tmp file system.

AIX - Installation - Preservation

This method replaces an earlier version of the BOS but retains the root volume group, the user-created logical volumes, and the /home file system. The system file systems /usr, /var, /tmp, /opt, and / (root) are overwritten. Product (application) files and configuration data stored in these file systems will be lost. Information stored in other non-system file systems will be preserved.

AIX - Installing the Base Operating System

AIX - Installing the Base Operating System

There are multiple ways to install the AIX® base operating system.

The Base Operating System (BOS) installation program first restores the run-time bos image, then installs the appropriate filesets, depending on your selections. The installation program automatically installs required message filesets, according to the language you choose

If you are reinstalling on an older system, the DVD media can only be used to boot or reinstall on 64-bit systems. To determine if your system is a 32-bit system or a 64-bit system, run the prtconf command with the -c flag.
