The WSUS server requests the metadata of the software update catalog from
Microsoft Update, which returns it to the WSUS server. If the synchronization occurs on
a configured schedule, the software update point performs a full synchronization and
applies all metadata changes, such as additions, modification, or removals. If you initi-
ate the synchronization manually, the software update point inserts only new catalog
metadata into the site database. This results in faster synchronization. The WSUS server
stores the metadata in the WSUS database, and the WSUS Synchronization Manager
continues to poll the WSUS server until synchronization is complete.

When WSUS Synchronization Manager polling detects that WSUS synchronization is
complete, it requests the software update metadata from the WSUS server and inserts
it into the Configuration Manager site database. When synchronization is complete,
the SMS_WSUS_SYNC_MANAGER component creates status message 6702. You also
can verify a successful synchronization by reviewing the site server's Wsyncmgr.log
for a reference to status message 6702. If synchronization fails, the WSUS
Synchronization Manager schedules another attempt within 60 minutes. Status mes-
sage 6703 also provides information about the failure. When the metadata synchro-
nization process is complete, you can view the software updates from within the
Configuration Manager console.
When the software update point that is located in the central administration site com-
pletes metadata synchronization, the metadata replicates to all child primary site databases
by using database replication. After data replication is complete for the site databases, the
child site's WSUS Synchronization Manager requests the WSUS database instance running
on the child site's software update point to initiate synchronization with the upstream WSUS
server in the central site. Child sites always perform a full synchronization. The WSUS
Synchronization Manager in each primary site then sends a replication request to any of its
respective child secondary sites that contain a software update point.
If you have a software update point that you do not configure to synchronize with an
upstream server (for example, a software update point that is located in a perimeter network),
you can export and import updates manually by using the WSUSutil tool. Using WSUSutil to
export or import metadata requires local administrative privileges on the WSUS server. You
must run the tool locally on the server. Use the following process to export and import the
metadata:
1.
On the export server, copy all the files and folders from WSUSInstallationDrive\WSUS
\WSUSContent\ to the import server. This ensures that locally stored updates and
applicable license terms are available to the import server.
On the export server, open a command prompt, type the following command, and
then press Enter:

wsusutil.exe export <packagename> <logfilename>
