I found this guide for upgrade. After the upgrade, can I delete safely the old DB product dir /var/oracle/app/oracle/product/12.1.0 ?

Yes, but do not simply delete it - deinstall it properly: http://docs.oracle.com/database/121/LADBI/remove_oracle_sw.htm#LADBI7824
Run $ORACLE_HOME/deinstall/deinstall
and follow the instructions.
