Actual quote of the GDPR:
(171) Directive 95/46/EC should be repealed by this Regulation. Processing already under way on the date of application of this Regulation should be brought into conformity with this Regulation within the period of two years after which this Regulation enters into force. [...]
I can't say for sure what's the scope, but I stand by my point that PART of it have a delay to get into conformity.
