Migration Considerations - IBM AS/400e User Handbook Manual

Upgrades to AS/400e server 8xx
From Models 600, 620, 640, and 650
1. Perform a model upgrade.
2. Buy processor feature on the "to" 8xx server.
3. Do a feature conversion from the current processor to an interactive card on the "to" 8xx
server.
From Models S10, S20, S30, and S40
1. Perform a model upgrade.
2. Buy an interactive card feature on the "to" 8xx server.
3. Do a processor feature conversion.
From Model S20, S30, and S40 Mixed-mode servers
1. Perform a model upgrade.
2. Do a processor feature conversion.
3. Do an interactive card feature conversion. The configurator will generate an RPO order to
add a zero-priced interactive feature specify code to the installed mixed-mode server prior
to the upgrade.
From 7xx servers
1. Perform a model upgrade.
2. Do a processor feature conversion.
3. Do an interactive card feature conversion.
From another 8xx server
1. Perform a model upgrade.
2. Do a processor feature conversion.
3. Depending on the "from" and "to" models, an interactive card feature conversion may also
be required.
Once within an 8xx server, performance upgrades are simply made through processor or
interactive feature conversions.

Migration considerations

• Most I/O supported on V4R1 or later is also supported on the 8xx models
– Features unique to 8xx servers are installed only in 8xx server system units and
expansion units.
– Features unique to "upgrade from" models are installed in migration and expansion
towers attached to 8xx servers.
