upgrade ebs 12.1.3 to 12.2 with database upgrade from 11gR1 to 12cR1


    Dear experts ,


    i have a R12.1.3 with 11gR1 running on OEL5.  I took a backup .


    I restored R12.1.3 APPS + DB  backup on new machine ( OEL 6 ).



    when i ran


    perl adcfgclone.pl dbTier


    RC-20200: Fatal: Could not find Unzip. At this time only Native UnZip 5.X is supported. ( perhaps this is due to OEL 5 and OEL 6 ).



    what is proper way and method to do this upgrade .....


    plz help.
