Re: JES3 to JES2 Migration (was JES2 to JES3 Migration)
As someone already mentioned, the JECL is different. It shouldn't be hard to write code to translate. The other issue is the class structure. JES2 uses an one character class on the JOB card. JES3 used the class on the JOB card or an eight character class on the //*MAIN JECL statement.

Re: JES3 to JES2 Migration (was JES2 to JES3 Migration)
We did a conversion 3 -> 2 many years ago, but it was more moving work from a Jes3 system to a Jes2 system, not converting an existing system from one to the other. It really depends on the complexity of the exploitation of the Jes3 constructs - How your Global/Local setup is, Do you depend on Setup to have resources in place, do you schedule with a scheduling package or use DJC's etc.etc. Biggest problem we faced was not the technical migration, but the education of our users of JCL and exposing them to new concepts. We had identified the risk there but it turned out to be a bigger challenge then we (the technicians) expected.

Re: JES3 to JES2 Migration (was JES2 to JES3 Migration)
In a past life, a group of sysprogs entertained the idea of migrating as a cost savings measure. The JECL and JOB CLASS changes were the least of our worries. Exits could be written to translate and map. As others have pointed out, 8-character JES2 JOB classes may reduce the need for custom code, as can software tools that identify and perform conversion (no pun intended). The bigger problem was JES3 functionality that systems and applications types alike exploited and the extent to which they did. I don't recall any technical hurdles we couln't clear - between already licensed, or readily available vendor (including IBM) software, plus a little custom code, there wasn't any JES3 function we used that couldn't be "replaced". It was the time to make the conversion and the cost of additional software that put the project on the shelf. YMMV. Migrating from JES3 DASD management to SMS (also mentioned to previously) helped, but, off the cuff, in no particular order, there are other features to consider, such as: - JES3 tape management - DEADLINE scheduling - DJC These have have viable alternatives, if you can spend the time and/or money. I agree a trip through the aforementioned Redbook(s), white papers, and a few SHARE presentations (the "bi-JESual" pitch comes to mind) will be well worth the investment in time.

So in JES2 jobs can either run where the JCL is converted or anywhere in the JESMAS. There is also the concept in JES3 that until all resources available, the job will not run. JES2 it can run and wind up waiting on resources. Those are about the differences I can think of off the top of my head.

Re: JES3 to JES2 Migration (was JES2 to JES3 Migration)
Cheryl. You may want to take a look at the IBM® Redbook® "JES3 to JES2 Migration Considerations": http://publib-b.boulder.ibm.com/abstracts/sg248083.html?Open And new functions (Job Execution Controls) have been introduced with z/OS 2.2 JES2. They are not yet mentioned in the Redbook, but may provide additional help with the migration.
