The OP needs to remember though that none of (or only very little of) that information is necessary. Assuming they share DASD, they can install the new z/OS 2.2 or 2.3 (I would go with 2.3) software for the z14 from the z10, after the first IPL of the z14 the cut-over from one to the other is dead simple and I (and many others) have done it lots of times. The architecture differences between the z10 and z14 are almost meaningless in that migration once they are both "up". Since they are so far back (release-wise) it's probably actually in many ways easier for them to migrate. As long as they don't try to do something really silly (like move as a sysplex) there should be very few (if any) issues with the migration. In fact, aside from local mods and exits it should be a very smooth migration. It's not that nothing can happen, but 1.12 is not really that old and converting from 1.12 to 2.3 is not really substantially different from converting to 1.13 or 2.1. Most, if not all, of the installed (vendor) software at 1.12 will work perfectly fine at 2.3. The IBM software is probably not a factor here as most will likely be replaced with the new OS version, but older versions of software (DB2, IMS, CICS) that will run on z/OS 1.12 will run perfectly fine on z/OS 2.3. Most other vendor software is equally migrated with very little effort (aside from reassembling some interface modules), so they should have no real problems.
If the OP has any questions on how to do this, he/she should feel welcome to ask me (or anyone else here) for help. It's no problem and I for one am always interested in hearing about how others go about their migrations. Just make sure you create a plan and follow the plan, don't try to "wing it".
