Proper procedure to update FreePBX distro v13?

Hi all,

Currently I'm using Elastix and would like to migrate to FreePBX. Just installed STABLE – 10.13.66 with Asterisk v11 on a VM and testing it. When there's a update for module is it ok to do the update and is it highly encouraged?
On Elastix it was not advised to do yum updates because it would break stuff.
Is there a yum update to on FreePBX? I could not see it.

Thanks for your time!
