This thread was originally motivated by needing to move from an older DS8 subsystem to a new one. We've done this repeatedly over the years with a combination of utilities and IPLs spread over several months. The goal this time was to do it in a big bang allowing for several hours of down time but otherwise all in one single window. The problem with our old way of doing things was that we would encounter many separate periods of DR risk where we could not recover the entire production environment. This time, by using PPRC with all systems down, there was no risk window since no data updates could occur in the meantime.
I'm happy to report that the new procedure worked. We abandoned the idea of 'comparing volumes' as taking too long with minimal payback. We shut it all down, synched up data volumes via PPRC, and IPLed everybody with an IODF that contained the new DS8 in place of the old. It went even smoother that we hoped for. Lots of planning and desk checking, no serious oversights. Thanks to all who contributed to this project! . .

We did the first 50+% this weekend (non-prod) in a little over four hours total. Forewent any compare utility as a costly and time consuming process of dubious value. Planning on the same strategy for the prod farm in the next month or so. Thanks to all who contributed. . .

No, you are NOT silly. Trust me. Actually I appreciate your posts here in IBM-MAIN. >I did get one off-list offer of a product that that sounds pretty >great, but we may just suck it up pretend we're grownups. 😉 Now and then I got similar off-list spam from IBM-MAIN members who wants to try sell me a [junk?] product or two. Like you, I just suck it up because I am grownup ( ok, sort off :-D ), or actually, I am not in a position to say to my management, "buy this spammy thing". Groete / Greetings Elardus Engelbrecht PS: some years ago, an IBM-MAIN member [0] spammed me for about 6+ months trying to sell me a crappy product despite that I politely told him the first time that I cannot accept his offers because I am too low in the food chain to accept/recommend his spam z/OS products. [0] - I see this spammer is silent/lurking on IBM-MAIN these last few months. Am I happy or am I that happy? ;-) ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
