AT&T 3.0 Upgrading from the Merlin Communications System, Convert the backup file, Install SPM

Completing the Upgrade

■To back up system programming from Release 2.1, you must use version 2.16 or higher of SPM.

3Install a Release 3.0 processor module. See Chapter 2, “installing the Processor.”

4Perform a frigid start (System Erase) to ensure that all system programming is returned to default values.

Use System Erase from the SPM Maintenance menu:

Maintenance →Slot →00 →Demand Test-System Erase (Line 5, left button) twice →Yes

See Maintenance and Troubleshooting for more information on System Erase.

5Convert the backup file.

This converts the backup file created in Step 2 to Release 3.0 format.

6Restore system programming; this puts the system in an idle state, and it cannot be used for the duration of the procedure. Refer to “Restoring from the System Programming Diskette” in Chapter 7 for more information.

Use version 3.xx or higher of SPM and restore the file you converted in Step 5.

7If applicable, program new features.

See System Programming for detailed programming procedures.
