See https://software.intel.com/content/www/us/en/develop/support/faq-purchasing-renewing-upgrading.html . You will probably find that, since your existing license was issued many years ago, upgrading will cost the same as a new purchase.

Please tell me the proper (usual) way to use/execute "compilervars.sh" and/or "ifortvars.sh."  Neither one is described in the install instructions.  My OS is Linux.  Thanks...

The Bash command is (i) A period, (ii) a space, and (iii) compilervars.sh, if that shell script is accessible through $PATH. If not, item (iii) should contain the path, either absolute or relative, as a prefix. You can also use the "source" command instead of item (i).
