We suggest to introduce new variable - ITM_KEPLER_DIR - for CPO based environment. This variable will replace already existing one: KEPLER_DIR
This variable will be set by users inside shell's startup script (take a look below - section Setting new location for Kepler installation).
Users will have to remove remove existing settings for KEPLER_DIR (take a look further in the page) or change it such way it points to location where IMAS based Kepler will be installed.
