I do not agree. A modern Text::CSV will use the XS-version if available and the Pure Perl version if XS is not available. So there is no need to "upgrade" your scripts. As per the docs:
Text::CSV provides facilities for the composition and decomposition of comma-separated values using Text::CSV_XS or its pure Perl version.

If there is anything you should do, then it is to replace Text::CSV_XS by Text::CSV to make your script more universally applicable.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
