Been there, done that, bought the T-shirt, wore it, and put it in a draw never to wear it again..
The path of choice given the hardware, software, expiration dates, and upward and downward compatibility issue is: z/VM 5.4 on z9 to z196 with the 14 APARs for 5.4 that support it and then move to z/VM 6.whatever but not 6.1 which: has a shorter expiration than 5.4 not much more function to offer than 5.4 does not run on a z9 anyway.

The problem is the upgrade path. We currently have a z9 so 6.1 is not an option on this machine. So when the time comes to swap CPU.s what OS can I IPL on the z196 that I have tested on the z9?

However, given the nature of changes made to z/VM 5.4 and 6.1 to support z196, you may encounter unexpected, undesirable side effects. Given upgrading to z/VM 5.4, or better yet 6.1, is straight forward, why not pursue this avenue rather than rely on knowns? Best Regards, Les Geer IBM z/VM and Linux Development
