Chapter 1. Overview of RISC-to-RISC Upgrades and Data Migrations The road map lists important considerations and activities that are critical to the successful model upgrade of a system. Although this road map is not designed to be an all inclusive how-to source for activities relating to upgrading your system, it covers the essentials by guiding you to the proper source. Follow all the steps in the order presented and notify your IBM® representative for assistance if you run into difficulties.
Contact your local IBM representative or authorized dealer for additional information on permitted upgrades. For servers that do not have an upgrade path, use the data migration section of this book. This would include scenarios such as an AS/400® Model 540 to an iSeries 400 Model 270. Why Upgrade from one AS/400 or iSeries 400 Server to Another iSeries 400 Server? You might ask yourself why IBM is doing this and why upgrade your server now? Most customers need to increase performance and add capacity.
Hardware Investment for Upgrading You may choose to upgrade your existing RISC system processor, or replace it with a new iSeries 400 model. In either case, you may keep most of the current system. The process of either an upgrade of your existing system or moving parts from an existing system to a new system, are called miscellaneous equipment specification (MES). MES denotes the process steps of an upgrade.
For Feature Code #0205, the customer must have purchased a new server with enough hardware and disk unit to hold all of the data from the ″source″ model as well as any new data including any required IBM software (OS/400 and so forth). Additionally, the RISC-to-RISC Data Migration process requires that the ″source″ model must be at the same version/release of OS/400 and Licensed Program Products (LPPs) as that of the ″new″ server which has been ordered/received.
How Long will the Data Migration Take? The data migration process includes planning, ordering, shipping, installing and testing the system. The following table shows approximately how long a data migration might take. Note: You should plan at least one additional hour of down time to upgrade the operating system for source systems not at the new server release level.
OS/400 Release Currently Installed V5R1 V4R5 V4R4 Book To Use For Upgrade and Software Installation If you have one of these releases installed on your system, your system already runs on the RISC architecture. Use this manual, iSeries 940x RISC-to-RISC Road Map, SA41-5155-05, for the upgrade. Use the manual Software Installation, SC41-5120-05, to replace the installed operating system and licensed programs.
Chapter 2. Planning Your Order for Upgrading or Data Migration Review this chapter as you identify a solution and again after a decision is made to verify the accuracy and completeness of the order.
configuration will perform with your current workload. The program temporary fixes (PTFs) are now available that include capacity planning information for the PowerPC processor models of the system. You can use Performance Tools to help you determine the proper configuration of the processor main storage, and disk resources that will meet your performance requirements. Performance Tools are the best source of information for determining what configuration meets your performance requirements.
Prerequisites Before Placing an Order This section will cover the prerequisites of placing an order to upgrade the system. These include software-related items, hardware considerations, system configuration considerations, and available services that everyone should know before placing an order. You may also need information about logical partitioning. Refer to the web site: www.as400.ibm.
v Verify with the original equipment manufacturer vendor that any non-IBM devices are compatible with the model upgrade and the new software release. v v v v Note: The customer should request written confirmation of this compatibility from the original equipment manufacturer vendor. The target system may have different power requirements than the source system. Appropriate planning and preparation by the customer is very important.
– Related support services – iSeries 400 and AS/400 solution services v Determine the responsibilities for all upgrade activities. These responsibilities include: – Outline the model upgrade activities and the person responsible for each activity, as described in Table 4 on page 17. – Develop an installation plan, a schedule of activities, and a checklist. See the SA Advisor in the Expert menu Application on HONE. Your IBM Representative may visit the Solutions Assurance Web site: http://w3.ibm.
v Be aware that upgrades to an AS/400 or iSeries server may require wiring changes to a building. For more information, see Technical Studio at http://www.iseries.ibm.com/tstudio/planning/plngstrt.htm. The customer should work with the marketing representative to schedule a system assurance meeting to review all of the following activities.
of these features. It should be used to ensure a valid configuration. The use of performance tools may also help in optimizing a configuration to match a specific set of requirements. Note: When ordering a model upgrade from a mixed-mode server (S20, S30, S40) to AS/400 7xx servers, an Interactive Specify code must be on the model Sxx inventory record prior to ordering the model upgrade.
v Planning assistance from IBM Global Services or from an IBM Business Partner may be very helpful if this is an unfamiliar area to the customer. Upgrading from a 6xx or 7xx to an 8xx Many installed AS/400 Models 6xx and 7xx, except SB1, can be upgraded to an iSeries 400 Model 8xx. 8xx models require V4R5 or later versions of OS/400 depending on the hardware function required.
