John is working for XYZ company. He received a tape from a customer that has the.dbf files and ORACLE_HOME database. He extracted the .dbf files from the tape to the server. After checking, he realized that the customer's DBA forgot to run preclone on the source database tier before taking a backup on the tape. To bring up the database successfully using adcfgclone.pl (postclone) on target, what action would you ask the customer's DBA to perform instead of requesting for a full backup again?
