Fs_clone Fails With txkCloneAcquirePort.pl does not exist

[UNEXPECTED]$INST_TOP/admin/install/txkCloneAcquirePort.pl does not exist. Cannot continue.
CAUSE
The template file (txkCloneAcquirePort_pl.tmp) is provided from CONSOLIDATED FIXES FOR R12.TXK.C.DELTA.4 Bug 18497540. This file is copied to the file system during the patch. When autoconfig is run this creates txkCloneAcquirePort.pl In this case this didn't happen so txkCloneAcquirePort.pl is missing.
As for 18497540 adpatch lgi file, this error noticed:
Will not apply txkCloneAcquirePort_pl.tmp: Files have same version.
 Patch  : $AD_TOP/admin/template/txkCloneAcquirePort_pl.tmp, v120.0.12020000.2
 On-Site: $AD_TOP/admin/template/txkCloneAcquirePort_pl.tmp, v120.0.12020000.2
As the versions of txkCloneAcquirePort_pl.tmp are the same, txkCloneAcquirePort.pl never gets created.
SOLUTION
1. Run autoconfig from the RUN File System (FS).
2. Make sure the txkCloneAcquirePort.pl file is created after autoconfig is run.
3. Run fs_clone again.
