The customer database on the option 51C can be sent to Northern Telecom
for conversion or converted on-site. If you choose to convert the database
on-site, refer to Table 9-2 to determine the appropriate conversion procedure.
The database conversion requires intermediate steps during which hardware
and software are upgraded incrementally.
Before beginning the database conversion procedure, obtain all of the
conversion disks, system software disks, and interim ROM and memory cards
required.
Note: Obtain extra-high-density floppy disks containing system
software from your Northern Telecom representative.
Perform the "Preconversion procedure" in Software conversion procedures
(553-2001-320) before beginning one of the following conversion
procedures. During the preconversion procedure, always enter LD 43 using
the source (option 51C) media.
