When I need to upgrade a Base release of IC5141, what's the method to upgrade this packages ? install USR(last version) or install all upgrade (USR1 USR2 USR3 USR(last version)) ?
install last USR (USR5), have BASE original CDs ready.
USR5 asks for BASE, take files from BASE, installs USR after.
after USR5 install and test, BASE installed no needed, can erase.
