Re: Z/OS 1.4 to 1.7 Migration
We are on z/OS 1.7 and have a project currently going on to migrate VS COBOL II to Enterprise COBOL. All VS COBOL II programs are currently executing okay under both z/OS 1.6 and z/OS 1.7. ___ Jim Petersen MVS - Lead Systems Engineer Home Depot Technology Center 1300 Park Center Drive, Austin, TX 78753 www.homedepot.com email: [EMAIL PROTECTED] 512-977-2615 direct 512-977-2930 fax 210-859-9887 cell This message may contain confidential information.

Re: Z/OS 1.4 to 1.7 Migration
Jim, Are these VS Cobol II program running under LE? If they are then you should be ok.

Yes, but you must supply a //STEPLIB for the run time modules. Brian -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: z/OS 1.4 to 1.7 Migration
You'll probably get 100 'it depends' answer on this one. How many CICS regions do you have? How many DBs, or other online things? How much batch? How much development? It's not a one size fits all situation.

Re: z/OS 1.4 to 1.7 Migration
I would say that you should be able to install and convert a test LPAR in a week or two if you don't have any of the JES2 exit conversion issues or something like that. We have a log of fairly closely integrated software for our size shop, so it takes us longer. Probably 2-3 weeks of work, but interspersed with some intensive head scratching. Of course, we always get pulled into the latest crisis or can't do anything due to production schedules. Your test time would vary, anywhere from none to user check-off and acceptance. Once you get it going in test, it should take about week of conversion prep, maybe a weekend to hot test production, then the real conversion the next weekend. It only took me a few days to get our test LPAR converted after the sandbox was well in place. Of course, then I discovered that we didn't get a Cobol compiler, ours had went out of support, so I'm waiting on that product to get ordered before I move on with testing. Our biggest issues were the JES exits, new versions of IOF, Vanguard Administrator, CA-MIM, ThruPut Manager and probably more. Some will get moved to production on 1.4 before we convert to 1.7. I plan for 6 months for a new OS migration. --- [This E-mail scanned for viruses by Declude Virus] -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
