When the profiles become invalid, the beta version that was distributed with that profiles in active could be used in normal?
Yes, don't worry about those builds, which were distrubuted earlier. Here is an official Apple distribution guide:
A provisioning profile appears invalid if it contains a revoked or expired certificate.
Expired certificates:
Certificate expiration or revocation
For standard developer program teams (those whose distribution method is the iOS App Store), expiration or revocation of a code signing certificate does not affect any apps that were signed with that certificate (this includes development builds, beta test builds, and live App Store apps). Its just an indication that the profile must be regenerated/updated to be associated with a new, valid certificate.
