About upgrading an existing S8300A to R3.1
Issue 9.1 June 2006 227
Release 3.1 upgrade scenarios
The upgrade procedures are slightly different depending on the upgrade scenario. The main
differences between the scenarios are summarized in Table 14
and are noted in the detailed
procedures.
The unshaded cells in this table are the most common and recommended upgrade scenarios.
The shaded cells are scenarios that are unlikely or not recommended.
The new S8300B media server will normally not have Communication Manager software
installed on it. If it does, remastering the hard drive is still recommended but could be replaced
with a standard upgrade.
If the current system has a 2.0.x release of Communication Manager installed, it is possible to
move the hard drive from the S8300A to the S8300B and then upgrade to 3.1. This saves a few
steps but it is not recommended for the following reasons:
● If the S8300 A hard drive is not moved, it provides a means to quickly revert to the original
configuration, if necessary.
● Hardware could be damaged in the process of changing hard drives.
● Only the Fujitsu hard drives can be moved.
● The hard drives on the S8300B have a larger capacity than the hard drives on the S8300A.
This larger capacity is not needed for R 3.1 but may be needed in the future.
