Do you want to continue to use the configuration files and encryption keys from the shared configuration location? If yes, the configuration files and encryption keys will be imported into the local configuration directory at %windir%\system32\inetsrv\config and will overwrite any existing configuration files and encryption keys. If no, the configuration files and backed up encryption keys in the local configuration directory will be used.
