Operating System Installation: Getting Started
Migration Installation
Use the following steps to migrate your current version of the operating
system to AIX 5.2.
For more information on Migration Installation, refer to the Migration Installation section in the AIX 5L Version 5.2 Installation Guide and Reference.
Refer to the Network Installation Management (NIM) section in theAIX 5L Version 5.2 Installation Guide and Reference,
if you are performing a network installation of AIX.
Attention: This procedure requires shutting down and reinstalling the base
operating system. Whenever you reinstall any operating system, schedule your
downtime when it least impacts your workload to protect yourself from a possible
loss of data or functionality. Before you perform a migration installation,
ensure you have reliable backups of your data and any customized applications
or volume groups. For instructions on how to create a system backup, refer
to
Creating System Backups in the
AIX 5L Version 5.2 Installation Guide and Reference.
Step 1. Prepare Your System
- Ensure that the root user has a primary authentication method of SYSTEM. You can check this condition by typing the following command:
# lsuser -a auth1 root
If needed, change the value by typing the following
command:
# chuser auth1=SYSTEM root
- Before you begin the installation, other users who have access to your
system must be logged off.
- Verify that your applications will run on AIX 5.2. Also, check if
your applications are binary-compatible with AIX 5.2. If your system
is an application server, verify that there are no licensing issues. Refer
to your application documentation or provider to verify on which levels of AIX your
applications are supported and licensed. You can also check the AIX application
availability guide at the following Web address: http://www-1.ibm.com/servers/aix/products/ibmsw/list/
- Verify that all currently installed software is correctly entered in the
Software Vital Product Database (SWVPD), by using the lppchk command.
To verify that all filesets have all required requisites and are completely
installed, type the following:
# lppchk -v
- Check that your hardware microcode is up-to-date.
- All requisite hardware, including any external devices (such as tape drives
or CD/DVD-ROM drives), must be physically connected and powered on. If you
need further information, refer to the hardware documentation that accompanied
your system.
- Use the errpt command to generate an error report from entries
in the system error log. To display a complete detailed report, type the following:
# errpt -a
- There must be adequate disk space and memory available. AIX 5.2 requires
128 MB of memory and 2.2 GB of physical disk space. For additional release
information, see the AIX 5.2 Release Notes.
- Make a backup copy of your system software and data. For instructions
on how to create a system backup, refer to the Creating
System Backups section in the AIX 5L Version 5.2 Installation Guide and Reference.
- Turn on attached devices if they are not already on.
Step 2. Boot from the AIX Product CD
- Insert the AIX Volume 1 CD into the CD-ROM or DVD-ROM
device.
- Reboot the system by typing the following command:
# shutdown -r
- When the system beeps twice, press F5 on the keyboard (or 5 on
an ASCII terminal). If you have a graphics display, you will see the keyboard
icon on the screen when the beeps occur. If you have an ASCII terminal (also
called a tty terminal), you will see the word keyboard when the
beeps occur.
Note
If your system does not boot using the F5 key
(or the 5 key on an ASCII terminal), refer to your hardware documentation
for information on how to get your system to boot from an AIX product
CD.
- Select the system console by pressing F1 (or 1 on an ASCII
terminal) and press Enter.
- Select a language for the BOS Installation menus by typing the corresponding
number at the Choice prompt and press Enter. The Welcome to Base
Operating System Installation and Maintenance menu opens.
- Type 2 to select 2 Change/Show Installation Settings and
Install in the Choice field and press Enter.

press Enter in the More Options menu . For more information about
the installation options available in AIX 5.2, see the Advanced Options section in the AIX 5L Version 5.2 Installation Guide and Reference.
- Verify the selections in the Migration Installation Summary screen and
press Enter.
- When the Migration Confirmation menu displays, follow the menu instructions
to list system information or continue with the migration by typing 0 and pressing Enter.

After migration is complete, access this information from the /tmp/bos directory.
After the migration is complete, the system will reboot. Configure the
system, as follows:
- On systems with a graphics display, after a migration installation, the
Configuration Assistant opens. On systems with a ASCII display, after a migration
installation, the Installation Assistant opens.
For more information on
the Configuration Assistant or the Installation Assistant, see the Configuring the Operating System section in the AIX 5L Version 5.2 Installation Guide and Reference.
- Select the Accept Licenses option to accept the electronic licenses
for the operating system.
- Verify the administrator (root user) password and network communications
(TCP/IP) information.
Use any other options at this time. You can return
to the Configuration Assistant or the Installation Assistant by typing configassist or smitty assist at the command line.
- Select Exit the Configuration Assistant and select Next. Or, press F10 (or ESC+0) to exit the Installation
Assistant.
- If you are in the Configuration Assistant, select Finish
now, and do not start Configuration Assistant when restarting AIX and
select Finish.
When the login prompt displays, log in as the root user to perform system
administration tasks.
