Enabling the multiple IBM Transformation Extender feature

This feature is enabled by making the names of the files and programs you are currently installing unique to the names used in other releases you have installed previously.

It is done by embedding the product version number, nnn, in the resource name, DnnnMAP. An example is to specify D810MAP as the resource name you are currently installing, while MERCMAP is the resource name used in your previous install.

With this resource naming convention, you must update the CICS resource definitions for each release of CICS Execution Option and duplicate the associated VSAM datasets.

The result is that a completely separate copy of the product is installed and none of its resources are shared with any other version of the product that exists in the same CICS region. The user Dynamic Storage Area used by CICS Execution Option components will effectively be doubled.
