Upgrading to Release 4.0
This section contains an overview of upgrading from Releases 1.0, 1.1, 2.0, 2.1,
and 3.0 to Release 4.0.
Although there are hardware modifications incorporated in Release 4.0, you can
still use the SPM software, available in both DOS and UNIX System (IS II or IS
III) versions. However, once the system is upgraded to Release 4.0, SPM is no
longer required for subsequent upgrades.
Upgrade Overview
You must perform the following tasks when upgrading to Release 4.0:
1. Install SPM Version 4.15 or later to back up and convert system
programming information, and to restore system programming
information after the Release 4.0 processor module has been installed.
2. Back up the system programming.
3. Install a Release 4.0 processor.
4. Perform a System Erase (frigid start).
5. Convert the backup file to Release 4.0 format.
6. Restore the system programming.
7. Program new features.
