Need to first delete the Librarian 4.3 and then reinit with Librarian 4.4
Create a copy of the CAIRIM member and create one that contains only the Librarian statements:
PRODUCT(CA-LIB43) VERSION(LJ43) INIT(LJ43INIT) -
PRODUCT(CA-LIB44) VERSION(LJ44) INIT(LJ44INIT) -
Restore the CAIRIM member to the full member and update the Librarian statement.
