Upgrades to iSeries servers 309
Draft Document for Review October 18, 2004 5486Up8x.fm
Upgrade considerations
Because there are differences in the physical packaging and underlying
technologies of the newer iSeries models, upgrades within or into these iSeries
models can involve a change to the system unit and input/output (I/O). Newer
hardware and applications can require newer levels of software. Careful planning
can minimize time, effort, change impact, and business cost.
Upgrades from the iSeries Model 810 and 820 into the Model 520, 550 and from
Models 810, 820, 825, 830 into the Model 570, use a
9406 machine designator to
allow IBM to better support the server. There is no physical difference between
the machine types for these models. Planning and configuration tools can be
used for configuration analysis by bypassing the difference in the 9402, 9404, or
9406 machine type designation. Refer to “Product Previews: Open” on page 68
for planning information about upgrades using a 9402 or 9404 machine type
designation.
The supported processor upgrade path for each model of the current Eserver i5
and iSeries product line is documented in IBM Eserver iSeries Supported
Upgrades, REDP-0322. This Redpaper is updated as additional upgrade paths
are announced or withdrawn.
Refer to “Planning information” on page 73 and “Withdrawn products” on page 76
to understand upgrade considerations. Refer to IBM Eserver iSeries Migration:
System Migration and Upgrades at V5R1 and V5R2, SG24-6055, for guidance
about upgrading to iSeries server models.
For software considerations, see “Supported upgrade paths” on page 591, and
“Current release to previous release support” on page 592. See
http://www-1.ibm.com/servers/eserver/iseries/support/planning/v5r3softw
are.html for upgrade considerations to i5/OS V5R3, or
http://www-1.ibm.com/servers/eserver/iseries/support/planning/v5r2softw
are.html for upgrading to OS/400 V5R2.
Note: IBM plans to use the same serial number in a 9402/9404 upgrade even
though the machine type designation changes to a
9406. Customers should
anticipate the change to a combined machine type/serial number as an
identifier and make appropriate arrangements in the customer asset tracking
system. A special process will apply in the unlikely event that a 9406 already
has the same serial number.
