Do you have to freeze a group or system when making changes? No.
Is it best practice to do so? Yes.
With the case of changing an existing group, freeze the group. If a mistake is made during the change such that a fault occurs, the group/service may failover, or shut down completely. Freezing the group stops VCS intervening until the issue has been resolved. At that point, best practice is to unfreeze the group, and test failover.
With a new group, it's less important to freeze anything, unless the new resources could have an impact on existing services. In which case, consider freezing those services.
