So, I have a system to patch from 11.1 to 11.2.
It should be straight forward, but one thing isn't clear to me.
Should I patch the database server first, even though it's already on
SyBase 12 OEM?

The upgrade manual isn't really clear on that point.
Has SyBase 12 OEM the same binaries in 11.1 and 11.2?
