R12.2.x Rapid Clone: Application configuration 'perl adcfgclone.pl appsTier' : Oracle Homes are unregistered from the global inventory

Performing Rapid Clone on the application server resulted in an error within few minutes that I triggered 'adcfgclone.pl'. The issue is with Inventory.

$ cd <COMMON_TOP>/clone/bin
$ perl adcfgclone.pl appsTier

Please note that 'fs2' is my RUN Edition in my environment.

Error from adcfgclone.pl:

Below Oracle Homes are already registered in the global inventory:
/wms/app/oracle/fs2/FMW_Home/Oracle_EBS-app1
/wms/app/oracle/fs2/FMW_Home/webtier
/wms/app/oracle/fs2/FMW_Home/oracle_common

Exiting Cloning...

Ensure that the above Oracle Homes are unregistered from the global inventory "/wms/app/oracle/oraInventory/ContentsXML/inventory.xml" and re-run adcfgclone.pl script

Solution:
Go to /wms/app/oracle/fs2/EBSapps/10.1.2/oui/bin (or $ORACLE_HOME/oui/bin) and run the following to unregister the Oracle Homes from the inventory.

$ cd $ORACLE_HOME/oui/bin
$ ./runInstaller -silent -deinstall REMOVE_HOMES={"/wms/app/oracle/fs2/FMW_Home/Oracle_EBS-app1"}
$ ./runInstaller -silent -deinstall REMOVE_HOMES={"/wms/app/oracle/fs2/FMW_Home/oracle_common"}
$ ./runInstaller -silent -deinstall REMOVE_HOMES={"/wms/app/oracle/fs2/FMW_Home/webtier"}

You may have to do the same when you build PATCH Edition (fs1 in my case).
