z/VSE 4.3 changes to installation and run-time support for CICS/VSE 2.3

A couple of weeks ago I blogged about the announcement of z/VSE 4.3 which will become available November 26, 2010. Now, here's an interesting support page that caught my attention via the twitter account of IBM_CICS and IBMzVSE for those who want to prepare an installation of z/VSE 4.3. If you are running CICS/VSE V2.3 and DL/I you surely have to take a look at this page : 'z/VSE 4.3 changes to installation and run-time support for CICS/VSE 2.3'.

The core of the message :
"If you are currently running CICS/VSE V2.3 and DL/I, you will not be able to do so on z/VSE V4.3. The highest supported z/VSE version and release when running both of these products is z/VSE V4.2.

z/VSE V4.3 also no longer provides product installation support for CICS/VSE V2.3. However, providing that DL/I is not required, IBM will not prohibit you from using CICS/VSE V2.3 with z/VSE V4.3. You will be able to install CICS/VSE V2.3 from an extended base tape supplied with a z/VSE V4.2 or earlier system. Alternatively, the CICS/VSE V2.3 sublibraries will remain in place if a Fast Service Upgrade (FSU) is used to upgrade to z/VSE 4.3. All other z/VSE V4.3 changes will be transparent.

z/VSE-supplied support for a CICS coexistence environment will be removed. However, you will still be able to run CICS/VSE V2.3 and CICS Transaction Server for VSE/ESA (CICS TS) V1.1.1 together on z/VSE V4.3."
