Upgrading the System Software
You can upgrade system software either from the external CompactFlash
card or by FTP, unless upgrading from a Release 1.x system. The internal
media in 1.x systems require repartitioning, which can only be done with a
CompactFlash card that has an “Initial Installation” software load.
Upgrading does not alter the currently installed database.
If you are upgrading to Release 4.0 and you are planning to use Mitel 53xx
IP phones, your upgrade procedure may vary depending on your system
configuration. The following table lists upgrade conditions:
Note 1: The FTP upgrade must be done twice to deliver 53xx set support.
Note 2: If your voicemail storage is excessive, there may not be enough
room to install the 53xx software. The upgrade procedure provides a
warning message in this case.
