Hi, There is absolutely no reason to make multiple jumps, especially when you can keep the environments contained as you had originally pointed out. It's a big jump, but no matter which point you picked for your jump point, it would still be a large undertaking. The good news is that it's been done hundreds of times, (well, 1.4 to 1.10 has, but I've found that 1.11 doesn't present any significant installation issues over 1.10).
I would suggest that you do get the migration guides for the interim releases and read the changes and procedures. Keep notes and you WILL find that some things are changed multiple times, in which case you might want to think about all of the changes and prepare for things. You didn't say what non-IBM vendors you had to worry about, and in most cases, that's the biggest worry. I've performed hundreds of upgrades and if you have any questions, please feel free to ask. One thing that you might have issues with (and this doesn't matter how many releases you jumped), is that there are some changes to the JES2 exits. If you aren't using any of them, then you can skip my warning. You can share catalogs and volumes, but if you are going to make a habit out of it, them make sure you have GRS or a substitute to protect yourself. If it's a controlled sharing, then you won't have anything to worry about. You can share the RACF database as well, but I have found that it's normally better to create a new one and fill parts of it from the old one instead of just copying the whole thing. it's not very difficult and it will allow you to remove a lot of built up crud from the previous releases. Since you are keeping things in monoplexes, you don't have to worry about the Couple datasets or anything. Your SMS and WLM environments should be audited, but only if you have been quite busy with those environments over the years because there are some slight changes that can bite you, but again, it's nothing major, nothing will die, you just might get some seemingly strange results. Your biggest obstacle will be taking advantage of all of the new stuff that has been added to the system in the newer releases. You may find that things you had to do with vendor software are no longer necessary so be mindful of whether or not you might really need the alternate vendor any more. remember, while it seems like a big deal, it's really just like any other upgrade, if you are careful and pay attention to the details, you will sail right through it.
