256 Logical Partitions on System i5
9.3 Migrating Linux partitions
This topic describes the options and requirements for migrating a Linux installation from an
iSeries server to an ^ System i5 system.
The first step in migrating a Linux installation from an iSeries server to an ^ System i5
is to upgrade to a Linux version that supports the ^ System i5 system.
Follow these steps to complete the Linux upgrade:
1. On your existing iSeries server, upgrade to a new Linux version that supports the ^
System i5 systems. Refer to your Linux distributor documentation for detailed instructions.
2. Replace your existing I/O device drivers with System i5 I/O device drivers. If virtual I/O is
being used, it must be configured in the OS/400 partition that provides the virtual I/O
device.
3. From the new Linux distribution, retrieve an ^ System i5 kernel and store it in the
OS/400 file system.
4. Configure the ^ System i5 partitioning. See Chapter 5, “Partition creation using the
HMC” on page 139 for instructions.
5. Migrate the OS/400 hosting partition to the new system.
6. Boot the Linux partition from the new Linux kernel.
For a full discussion of Linux on ^ System i5 systems, review the IBM Redpaper,
Linux on i5: Implementation Guide, SG24-6388.

9.4 Migration scenarios
This topic presents the process and tasks involved in migrating to System i5 for two
scenarios. The first is an upgrade from an 810 with two OS400 logical partitions to a 520
System i5 system. The second scenario in an upgrade from an 825 with three OS400 logical
partitions to a 570 System i5 system.
Attention: Some IBM services are billable to the customer. Prior to starting the upgrade,
all details of the upgrade should be discussed to determine the scope of the services
performed by IBM. This can be done during the pre-sale Solution Assurance Review.
