IBM AIX5L, AIX 4.3 manual Migration sources, Preservation installation

Following are some of the tasks you might perform, based on your specific environment, when selecting a new and complete installation.

￿Set the system date and time for your time zone.

￿Set a root user account password to restrict access to system resources.

￿Confirm or change the install device you want to use for installing additional software. The device may be a CD-ROM, a tape drive, or a local or remote directory.

￿Check the system storage and paging space needed for installing and using additional software applications.

￿Set your National Language Support (NLS) environment.

￿Import user-defined volume groups.

￿Create user accounts and passwords.

￿Install third-party device drivers (for example, LAN printer server).

￿Set your system network configuration (if applicable).

￿Create local and remote terminals.

￿Configure local and remote printers.

￿Install and configure additional LPPs.

￿Install and configure third-party software.

This method can be suitable for a stand-alone system with a simple configuration.

2.3.3 Preservation installation

Preservation installation was the default installation method of the Base Operating System (BOS) for systems running AIX Version 3.1. Since AIX Version 3.2, the migration installation is the default and recommended method. However, there is still the option to migrate to AIX 5L by using the preservation installation method.

With a preservation installation, the contents of /usr, /, /var, and /tmp will be deleted. The process will save the previous paging space and dump device, /home, and other user-created file systems in rootvg.

User-defined volume groups (non-root volume groups) will be preserved and activated automatically after the preservation installation completes. Before mounting the file systems belonging to these user-defined volume groups, you need to recreate the file systems′ mounting directories that were removed during the installation (directories under / or /usr, for example).

Configuration files, with the exception of /etc/filesystems, will be deleted. If you want any additional configuration files to be saved during the preservation installation, you must edit the /etc/preserve.list file on your existing AIX system, and add the full path names of the configuration files you want to save. There must be sufficient disk space in the /tmp file system to store the files listed in the /etc/preserve.list file.
