The Reinitialize Subscription(s) dialog box allows you to mark all subscriptions to a publication for reinitialization. Reinitialization involves applying a snapshot to each Subscriber. The Distribution Agent performs reinitialization for subscriptions to transactional publications, and the Merge Agent performs reinitialization for subscriptions to merge publications.
Options
Use the current snapshot
Select to apply the current snapshot to each Subscriber the next time the Distribution Agent or Merge Agent runs for the subscription. If there's no valid snapshot available, you can't select this option.
Use a new snapshot
Select to reinitialize all subscriptions with a new snapshot. The Snapshot Agent generates the snapshot. You can apply the snapshot to each Subscriber only after the Snapshot Agent generates it. If the Snapshot Agent is set to run on a schedule, subscriptions aren't reinitialized until after the next scheduled Snapshot Agent run.
Select Generate the new snapshot now to start the Snapshot Agent immediately.
Upload unsynchronized changes before reinitialization
Merge replication only. Select to upload any pending changes from the subscription databases before the data at the Subscribers is overwritten with a snapshot.
If you add, drop, or change a parameterized filter, the reinitialization process can't upload pending changes at the Subscriber to the Publisher. To upload pending changes, synchronize all subscriptions before changing the filter.
Mark for reinitialization
Select to mark each subscription for reinitialization. After a valid snapshot is available, the next time the Distribution Agent or Merge Agent runs for the subscription, the snapshot is applied at the Subscriber.
