Standard upload
New system software is uploaded in different phases. The Upload Manager moni-
tors the system software copying process from the PC to the communication
server. The version transfer is monitored by the new system software.
Sequence phases for the standard upload:
• Preparation phase:
The Upload Manager prepares the communication server for the transmission of
the new system software.
• Upload and backup phase:
The new system software is transferred to the communication server's file sys-
tem in compressed form and stored there. The previous system software re-
mains stored as a backup.
• Software update phase:
The current system software is replaced by the freshly loaded system software.
• Restart phase and version transfer:
The communication server is restarted automatically. The boot software starts
the new system software and runs a version transfer at the same time.
• Monitoring phase:
During the monitoring phase, the new system software is active, but the old re-
mains. In this phase, the old system software can be reactivated at any time with
a
Rollback
. When the monitoring phase is finished, the old application is deleted.
