I see in the docs that the only path is a new box, but has anyone done an in place upgrade as I thought some here had done so. (I searched but came up with everything else but)
upgrade path from Mobility 2.x/14.x to 18.x is to create a new Mobility server and install Mobility 18.x on that server.
while that is a good idea for any system that has been up a while, is it really needed, and why?
The client I am looking at has a fairly new GMS box on SLES12.4 (built as 12.3 and soon updated to .4), so am trying to understand how necessary is it for us to go through that effort. I was also hoping to get this one upgraded before 'Fall back' as I'll be in a good spot to monitor this system during that repeated hour where I've seen GMS problems before (one part appeared to stop running in that hour, please set your GMS logging to debug during this time if you can).
