1. d
2. d (migration installation = aix3.2, 4.1, 4.2, 4.3 to 5L... so i think preservation installation is better answer here.)
3. don't know. a or d??
4. b. (it's a new sys with new disk. everthing is new so rmfs doesn't matter.)

ps: can you still take 191? i heard it's no longer available after Sep 9th. you need to double check with IBM.
