The concession that ASM plays no part in making the move from one OS platform to another wasn't speculative.

The quality of the speculation about what I think Bob was getting at is irrelevant... see below.

Er, the point is that if I need to get clarification from the OP, so does anyone that assumes that "migration" referred to migration between storage vendors!

Ultiimately, it doesn't actually matter whether my assumption is the right one or not: I wasn't the guy condemning someone else for being 'ignorant' about a topic on the basis of mere assumptions about what the topic actually was that he was supposed to be ignorant about!
