The issue is not technical, it is a business issue. The traditional method of z/VM maint is to bring up the new release as a guest under the current release. Migrate all of the guests on the current release to the new release, and shut down the "old release". This will promote the "new release" to be the true hypervisor. This obviates the technical necessity for multiple LPARs.
However, if that LPAR needs to be shut down for any reason (Disrputive microcode is the only thing I can think of at the moment), you have lost all applications. You haven't stated if there are multiple CEC's involved or just LPARs on a single CEC.
