One small item to consider... zVM 4.x was the dual image release. There are 2 different supervisors. A 31 bit and a 64 bit one. As you will be going to a z9, you are required to use the 64 bit one. No big deal.
Except if you have something that is depending on your old supervisor. A patch you applied.. Chaining thru the control blocks.. The default on the z/890 was the 64 bit supervisor. If for some reason, you were running the 31 bit supervisor on your z/890 (which you can select), your only option is the 64 bit supervisor on the z9. Again, no big deal. Just something to keep in back of your mind, after conversion.

We'll switch over to 5.3 later in the summer or fall. Jim
