It should be ok with most current apps, but I would run them on a test 
server first if it's something mission critical. Php's site has 
migration info (http://www.php.net) which should be helpful for 
custom scripts. Also the vendor sites should let you know if they 
will work with php5. I haven't run into anything that won't in quite 
a while, but your mileage may vary :-)

You will need to completely remove php4 and ALL extensions then 
rebuild them with php5. FWIW, their site says that they will still 
have critical patches for a while, but all official support stops at 
the end of December.
