Whenever you're migrating from one OS to another, there's not specifically need to update the entire installation. There's a procedure in the documentation to migrate the SSdb and DDM from one installation to another. This is the way that I usually upgrade and change the OS on the machines.
If you don't have any customisations in your SSdb maybe it would a better idea to migrate the configuration using Modeling Gateway. This way you skip some upgrade steps. Check the compatibility between versions and you can install directly 10.4 and load the information from an older version. I've seen recently some technical documents with some errors related to modelinggateway and imports, errors due to changing of some attributes ids.
Another aspect would be that starting with 10.2 huge landscape mode was introduced, allowing you to have 10.000 devices and 1.000.000 models on one landscape. It not possible to migrate an old landscape (pre 10.2) and have the new huge landscape mode.
Fresh install would be better to loose the noise from the old installations. It's a good opportunity to start a clean installation.
I would test the migration using modelinggateway as migration tool, considering all the above mentioned aspects.
9.2.x is not in support for some years now, so I doubt you'll have any support from Broadcom over this. It would be under best effort support, if they have the time. Way to complicated to go trough several OS upgrade and several in-place applications upgrade in the same time and having it working. Furthermore doing this having no support if problems arise.
Test everything in advance, install new machines with the latest OS supported and then switch off the entire old system and start the new one. That would be the easiest way possible.

Hi,
I am planning a migration of Spectrum off Windows 2003 to Windows 2016 and to upgrade Spectrum from 9.2.1.6 to 10.4. If you have insights or advice you can offer please do so.
My plan is currently as follows:
Step 1 Migrate existing Spectrum 9.2 to New servers (Windows 2016)
Create new Windows 2016 Servers
Migrate data as per "Migrate and Upgrade on Windows"
Perform installation of Spectrum 9.3 on each of
Primary SpectroServer
Secondary SpectroServer
OneClick Server
Step 2 Upgrade Fault Tolerant System using the new servers
Follow procedure in "Upgrade Fault-Tolerant SpectroSERVERs and OneClick Web Servers" replacing each server with the new upgraded server
Step 3 Upgrade to Spectrum 10.2
Follow the procedure in "Upgrade Fault-Tolerant SpectroSERVERs and OneClick Web Servers" using in-place upgrades
Step 4 Upgrade to Spectrum 10.4
Follow the procedure in "Upgrade Fault-Tolerant SpectroSERVERs and OneClick Web Servers" using in-place upgrades
One concern I have is that it may be necessary to use Windows 2012 as an intermediary step to maintain support for spectrum.
Thanks
Paul
