Can I upgrade from MSTP 9.2.03 to MSTP 9.8 directly on 15454 M6 Multi-shelf nodes?

The upgrade document looks like you can from the sub section for 15454 M6 nodes but it is not real specific.

please check this tool:

it's very useful.

there are points to keep in mind while doing upgrade from 9.203 to 9.8

 To upgrade a multi-shelf node from R9.2.0 and earlier, perform a step upgrade to R9.2.1 and then to R9.4.0 , R9.6.0, R 9.6.0.3, or R 9.6.0.4.

i would say, upgrade your node to 9.403 or 9.60 than go for 9.80,

don't do upgrade directly to 9.80/
