We just did one and it was simpler than expected.
Documentation seems scarce on Server Edition at this point and we decided to use the upgrade procedure outlined in Technical Bulletin 150 instead of those in the Deployment Guide. It worked exactly as documented.
[Attach a monitor, keyboard, and mouse to the server (a step we didn't see listed in any of the documents that detailed upgrading) before you boot it to read from the DVD. Make sure the ISO extracts as it burns to DVD too.]
10.8 Server Edition Upgrade
Avaya IP Office Server Edition was released with R8.1 and two different upgrade
options are available. In both cases the software will need to be downloaded from the
Avaya support website. Due to the size of the software image it is provided in 2-parts
which need to be saved to disk and then uncompressed before the ISO image is
used.
• Local Upgrade – Using the ISO image burnt to DVD the Server Edition
system is booted from the DVD. You will need to go through a couple of the
setup screens (language, keyboard, EULA), the system will then detect that a
previous version is already installed and will offer an upgrade option. Select
the upgrade option and then follow the on screen prompts.
This will upgrade the O/S (if required), the IP Office, the one-X Portal, the
VoiceMail Pro and any other components necessary. The process typically
takes around 30-40 minutes, at the end of the upgrade the DVD is removed
and the system is restarted.
If there are no expansion systems in the network (Secondary Server, Linux
Expansion or IP500V2 Expansion) then no further action is required. If there
are expansion systems in the Server Edition network then once the Primary
Server has been upgraded you must log in to Web Control on the Primary
Server and go to the Solution Management page. From here you have
buttons which allow the upgrading of the expansion systems.
