You can use this road map as a guide to upgrade from an IBM POWER®5 or POWER6™System p® model or hardware
feature or from an IBM POWER5 or POWER6System i® model or hardware
feature to a POWER6Power Systems™ server.
Enabling POWER6 systems to support AIX, IBM i, or Linux on Power 520, Power 550, and Power 570 servers
You can upgrade the server firmware of an IBM System p5709117-MMA system to an IBM Power 5709117-MMA system. You
can also upgrade the server firmware of an IBM Power 550 Express™8204-E8A system to use IBM i logical
partitions and upgrade the server firmware of an IBM Power 520 Express8203-E4A or an IBM Smart Cube 8261-E4S system
to use IBM i logical partitions.
Upgrading the system and data migration
You can upgrade from an IBM POWER5™ or POWER6System p model or hardware
feature or IBM POWER5 or POWER6System i model or hardware
feature to an IBM POWER6Power Systems server. For
certain systems, you can also upgrade the server firmware so that
you can use IBM i logical
partitions and your system can create and run combinations of IBM i, AIX, and Linux® logical partitions.
Data migration
Perform a data migration only if you are moving to a new
model with a different serial number for an operating system.
