And z/OS 1.4 has been out of support for a while unless you're paying through the nose for continued support as we were. 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.

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
