worried about updating to 7.2.1 beta?

I already have a live site with 7.2 and worried about updating it to the new beta. Would this cause any problems if i was to update it? Also does this run via install again when updating it? or will it run as normal when uploading the files to the dolphin directory?

Ive not really updated it to a beta version before. And considering it is a live site .. would it damage any client data when updating?

 IMPORTANT: this version is not suitable for production sites and there will be no upgrade packs for it.

if you have read good then you know that you cant upgrade the beta wait til release version are there
