6.8 Upgrading the software of a simplex Aastra system R5.2
Note : See also Aastra Management Portal operating manual.
6.8.1 Principle
This procedure applies to systems already working in R5.2 and which the user wishes to
upgrade to a release above R5.2.
A backup must be made before starting the upgrade procedure.
The software licence associated with the working R5.2 will be retained for upgrade to later
releases.
The different modes are:
•From AMP,
• From Aastra Management AM 7450 (TBC).
Nota : During the restart phase following the upgrade phase, communications are
interrupted.
6.8.2 Upgrading the software from AMP
The function is executed from the AMP, in the menu SYSTEM>Software
maintenance>Upgrade.
The upgrade concerns either the Aastra 5000 application, or the OS version, or both.
The procedure is the same as the one described in Section 6.7 (except for the licences
which will not be required during switchover because the system keeps the ones obtained
during the first upgrade to R5.2).
