The CZ is updated and those changes are then filtered down to the IZ and NZ.  From Ex Libris: "Alma handles 50,000 changes at a time. If more than 50,000 changes are to be performed in the Community Zone, Alma launches an additional job to handle the rest of the changes."

If there are a large number of changes, the job that “synchronizes changes from the CZ” will be broken up and run over the course of several nights.  You can check on the progress of this job in the Monitor Jobs > Running tab. If you see a job, Synchronize Changes from CZ = Pending, the update has not finished. You can see the changes in the CZ but they may not have been applied locally yet. If your library has been expecting changes from a specific weekly update, wait until the update is complete to check on the changes.
