Upgrading from...
MICS 7.0
Legacy hardware and software upgrade notes:
Ensure that you maintain an accurate record of your existing
system programming so that you can plan your new system
programming appropriately.
If you have a Norstar system with a Modular 8X24 Key
Service Unit (KSU), you cannot upgrade your software with
the Upgrade Tool. If you want to upgrade to MICS 7.1, you
must replace your older Modular 8X24 KSU with the current
0X32 ICS (Integrated Communication System), and then
program the system.
