Before deploying the package into an installation, the utility creates a rollback directory containing the backup copy of files from the current installation which will be used incase of a rollback action. You can rollback your configuration to that in your rollback directory, only if the version of your current installation is the same as the version of the installation when the rollback directory was created.
Note:
Soft links created for product related files in the UNIX environment are not handled by sm_deploy utility.
