noone has your exact configuration, so the only way to know if it will 
for sure work for you would be to test it on a staging server configured 
identically to your production server, or at least, make full backups of 
your system so you can restore it if something goes wrong.

generally, updates are safe if your system is clean and doesn't have its 
system components polluted by non-distribution code.
