Let's assume you have a Staged catalog version and an Online catalog version for a product catalog, and the Staged catalog version got corrupted (and cannot be easily fixed manually), but Online still contains good data.
What is the easiest way to do a full catalog sync from Online to Staged (as a one-time measure)? What is the easiest way to create a sync job from the existing Staged->Online sync job which syncs in the opposite direction?
Cloning the sync job and changing it to sync in the opposite direction works, but you get a ton of errors, because the items already exist in the target catalog version (Staged) and there are no ItemSyncTimestamp items yet that indicate that a sync was already done.
Clearly, for syncing from Online to Staged, the flag to remove items in the target catalog version if they are not in the source catalog version must be activated, and a forced update would need to be used.
