Description of replacement scenarios
When the S8300 hardware is replaced, you need to reconfigure the S8300 Server. The easiest
way to do this is to back up the configuration data from the original hardware and do a full
restore to the new hardware.
Scenario 8 is the common replacement scenario in which the old and new hardware and
software versions are the same.
However, for scenarios 1, 3, and 6, the original and new hardware are running different software
releases. In these scenarios, you will need to do a software upgrade (on the original hardware
for 1 and on the new hardware for 3 and 6) to make the software releases the same.
For scenario 6, since the hardware is not functional, you cannot do a backup so you will restore
the latest available backup. To do these upgrades, you need to have a CD containing the
appropriate server software load. The software load will typically be the latest release of the
software, but it could be an earlier release depending on what is required to make the software
releases the same on the original and new hardware.
For scenarios 2 and 5, the original and new hardware are running the same software release so
no upgrades are required. For scenario 5, you will restore the latest available backup.
For scenario 4, you cannot use the latest available backup to restore the configuration data.
(You cannot upgrade the original hardware or backup the configuration data because the
hardware is not functional. You cannot do a full restore of the latest available backup because
the original and new hardware have different software releases). In this scenario, you must do a
full configuration using the Avaya Installation Wizard or using Configure Server Web page on
the Communication Manager System Management Interface Web page and restore just the
translations and Communication Manager Messaging files from the latest available backup.
For scenario 7, you (and the customer) do not know the software release on the original
hardware, and you are unable to check the software release because the hardware is not
functional. In this case, you must follow the replacement procedure in scenario 4, with the
additional step of upgrading the new hardware to the latest software release, if that software
release is not already installed on the new hardware. This upgrade step ensures that the
system is not be downgraded in case the original hardware had the latest software release
installed.
Note: If you have a set of backup files which will be used to restore the server, you can
determine which Communication Manager software release was running on the
original server at the time of the backup set was created.
After the Communication Manager software is installed to the replacement S8300
server, you can use the View/Restore Data, preview capability to determine what
Communicatioin Manager software was running at the time the backup set was
created.
