If the DR site is running you under VM (as most do because it allows you to keep your CPUID the same as your production system), then things will work perfectly and you can not worry about anything. If on the other hand you are going to run on some z/196 LPAR directly, then the success will depend on what you are expecting to work.
Will it IPL, yes, but many things you may want to do will probably not function simply because the support code just isn't going to be there for you. Things like EREP and RMF will completely fail (which you probably could care less about). Your WLM constructs will probably fail,but WLM itself will still function, but unless you are using some of WLM's extended features, you probably won't care about that either. If you aren't running under VM, the chances of your I/O configuration just happening to match the z/196 is remote anyway, so you will be making some drastic changes just to try to support the HCD requirements (You can't generate a IODF from z/OS 1.4 that will work on a native z/196, but I have ways around that if you "really" need to do it). If you can't guarantee that you will be coming up under VM, then the "safest" bet for you is to migrate to a higher level of z/OS. The cost is minimal and any products that are increased in cost will probably be cancelled out by the ones that are cheaper or free now. I don't know what machine type you are running on now, but it would (probably) be safe for you to migrate to z/OS 1.10 through 1.13 for most of them (including the original z/800). My specialty is helping people do those kinds of migrations and as such I have compiled a huge database of what software will work under what releases of z/OS. For the most part, unless the software you were running on z/OS 1.4 was already out of date when you installed it originally, it will probably continue to function on z/OS 1.10+. You may have some other things that need to be tweaked (i..e JES exits etc.) but chances are that you are fairly vanilla by now to make getting off that mainframe easier anyway and for the most part the conversions of that type of code is seriously simple. You can convert as a project for yourself, or you can have a company like mine do it for an extremely low cost, (or you can have IBM do it for an arm or a leg:)). If you need help doing this on your own, or if you want us to do it for you, please feel free to contact me off list. I have helped close to 100 sites do these kinds of migrations, even the ones that did it themselves as several on the list will be able to verify, and if there are any questions I can answer for you, please feel free to contact me.
