Introduction
This chapter describes upgrading an existing main office and its associated
branch offices from CS 1000 4.0 or CS 1000 4.5 to CS 1000 Release 5.0.
If, in a given network, there is one or more CS 1000 4.0 Branch Offices,
or one or more CS 1000 4.5 Branch Offices, all Branch Offices must be
upgraded to Succession 4.5 software before upgrading the main office to
CS 1000 Release 5.0.
When the Branch Office is being upgraded, the following components are
not affected:
• telephone services between MG 1000B IP Phones in Normal Mode
• telephone services between MG 1000B IP Phones in Normal Mode and
main office telephones or trunks other than those to the Branch Office
Selecting to migrate your system to an MG 1000B will mean you are
effectively decommissioning your existing system software. Once your order
is processed, your existing system Site ID/Serial number will be marked as
decommissioned in Nortel’s software history database. The purchased
software licenses on your existing system (and the "right-to-use" for the
software) can be transferred to the target CS 1000E main system. You
can also transfer your Applications to the target CS 1000E as part of this
process if you wish (assuming they are supported). If you want to move
some Applications to a different system, please do that in advance using the
regular Applications Transfer process.
