How to switch from SMB to NFS?


I’ve been using my Raspberry Pi with Raspbmc for some time. First I was using network share, and later on I bought Qnap NAS, but stayed on SMB. And I am wondering if there is a fast way, to switch from SMB to NFS, to check how it will behave, if there will any differences etc. I’d like to keep using mysql database.
I wonder if it’ll be enough just to turn off SMB shares and add NFS shares and populate database? Or is there a different way?
