License Preservation
Users may choose to preserve the existing license file when applying a new license file.
 This facilitates a rollback 
to the original file, if the replacement file is problematic.
 
Unix-like OS (AIX, HP-UX, Linux, Solaris, etc.)
Use tar or gzip to copy your license file into an archive.
 For example:
     
tar cvzf virtuoso-lic.tgz virtuoso.lic
