How to run autoconfig if we lost adautocfg.sh script from $ADMIN_SCRIPTS_HOME location?

echo $CONTEXT_FILE

/u01/devapp/inst/apps/DEV_seefdev/appl/admin/DEV_seefdev.xml

cd $AD_TOP/bin

./adconfig.sh -contextfile=/u01/devapp/inst/apps/DEV_seefdev/appl/admin/DEV_seefdev.xml

Once this is executed, the original adautocfg.sh is also created in default location.
