You will not be able to bring across your JES spool you will have to offload then reload to your new spool. To fall back you would have to have dups of your 3rd party data sets because I am sure you will have recompile/reassemble some modules.You will not be able to use the same TSO profs on a fall back. SMPE may give you some problems installing 1.8 on a 1.4. If you have DB2, CICS, or another data base type product check for maint. that you will need for 1.8.

Are you in 31 or 64? We had a problem, in a simple monoplex, going from 31 to 64 in z/OS 1.4 with a 3rd party product doing some nasty things in storage. Bu Dante <[EMAIL PROTECTED]> wrote: We run on z/OS 1.4. I know recommended upgrade is to 1.7 (N+3). Our system is simple and nothing is shared. There are many 3rd party products running on 1.4 but up to date. Since 1.7 support will run out in September this year, we would like to upgrade now to 1.8 or 1.9 if there are no major issues. Has anybody done this and what are some of the problems encountered and is fallback possible? ---------------------------------------------------------------------- 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 ---------------------------------------------------------------------- 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
