Upgrading Linux from CentOS 6.3 to 6.7 - Cacti concerns

[GreyHunter]

Good day gentlemen,

I hope this finds you well.

I'm planning to do OS update from CentOS 6.3 to latest 6.7. Is there any concerns regarding my Cacti setup?

PHP and MySQL will be updated too, So is this going to break current configuration?

I'm using Cacti version 0.8.8a (CactiEZ)

Thanks.
