(7)In order to ensure a smooth transition from the regime applicable under Directives 93/23/EEC, 93/24/EEC and 93/25/EEC, this Regulation should allow for the granting of a derogation for a period of up to one year and, in the case of sheep and goats, up to two years, to Member States where application of this Regulation to their national statistical systems would require major adaptations and would be likely to cause significant practical problems.
