There haven't been many wide-sweeping changes between 5.8 and 5.22 that would immediately break your program.

The most obvious changes would be the much better handling of Unicode.

The annoying stuff for migrating to a new Perl version is that you need to collect all the missing prerequisites that likely have accumulated in your old Perl installation. I keep track of my prerequisites in a Makefile.PL even if I don't intend to distribute the software ever. This makes reinstallation of all prerequisites as easy as:

cpanm --installdeps .

You can test the migration to a new version of Perl by installing a separate version of Perl using perlbrew. That way, you have a low risk of ruining your existing installation.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
