Convert Appleworks .cwk files on Mac OS 10.11.6 to Pages?

Need to convert old .cwk files to Apple Pages on Apple El Capitan OS 10.11.6

Hello,

  • if you find a version of iWork 09 or a previous version (but not a newest version), it must be able to open
    AppleWorks 06 word processing file in Pages, …
  • using LibreOffice, normally, you can ask it to open your files, then to export them as Microsoft Word files …
