This action marks each subscription to be reinitialized from a snapshot the next time its Merge Agent runs. Subscriptions that were initialized manually when they were created will also be reinitialized. If you do not want a subscription to be reinitialized from a snapshot: drop the subscription, reinitialize the subscription database manually, and create the subscription again.
