I would say that a bit of both will be necessary. In order to prevent shocking the plant, you should do no more than 1/3 of this pruning at a time. This means taking parts of the plant, slowly, over time.

This may take a couple of years, if the shrub is excessively large, since you will only want to prune during the proper times. You will want to catch them right after flowering, so that you don't destroy next year's flower buds.
