Yes. Before upgrading, please read the entire page here:
  http://www.pmwiki.org/wiki/PmWiki/Upgrades

You may also want to read the Release notes since your previous working  
version:
  http://www.pmwiki.org/wiki/PmWiki/ReleaseNotes

but the most critical changes are outlined in Upgrades.

PHP 5.3, 5.4 and 5.5 introduce some "features" or changes, or bugs that are  
backwords-incompatible so we had to continuously update PmWiki 2.2.X to make  
it work with both earlier and current PHP versions.

If you are missing sections of some pages, or see blank pages, it is  
probably a problem with htmlspecialchars() or iconv() which was fixed a  
while ago.

If your skin is not displaying correctly, see if you have defined some  
variables in config.php pointing to the old server URLs. The variables  
$ScriptUrl, $FarmPubDirUrl or $PubDirUrl. Other reason for the skin not  
displaying properly may be directory permissions on the server: both the  
server process and the PHP interpreter need read access to the files in the  
pmwiki/pub directory tree.

Otherwise, describe precisely what problems you see and what we can do to  
reproduce/experience them.
