Description of changes:

WEDNESDAY:
Enhancements to the existing Directory Sync task on the PRODUCTION Hub. These enhancements will allow the Hub to sync with the eHealth Exchange and Carequality directories in a recurring task daily rather than manually.

Message Transform updates for documents exchanged with Carequality gateways. This will only affect eHealth Exchange Participants that use the eHealth Exchange as their implementer to connect to Carequality.

These two changes have been heavily tested in the eHealth Exchange non-production environments.

THURSDAY:
Updates to the recurring task that purges clinical documents from the PRODUCTION Hub logs. The message trace will still be retained for seven days for troubleshooting purposes, but the clinical documents within the messages will have a one-hour retention period.

Scope:
These changes will be applied to the eHealth Exchange Hub PRODUCTION environments as outlined above.

Impact:
We do not anticipate any other service interruptions in LIVE during the maintenance event; Real-time routing of messages through the Hub will be unaffected.

Support:
eHealth Exchange staff will monitor administrator@ehealthexchange.org during the upgrade window to address any questions or concerns.

ADDITIONAL INFORMATION AND REMINDERS:
The eHealth Exchange Hub team has implemented a recurring weekly scheduled maintenance window each Thursday evening at 5:00pm ET for all non-urgent events.  The duration of each maintenance event will be determined by the respective changes for each event, and details will be communicated out to all Participants at least 48 hours prior to the event.  If there are no changes for any given week, then the maintenance event will not occur, and no notice will be sent. Also please note that Operating System and similar updates that do not require a service outage, and do not require changes to the application layer, will be performed during this scheduled maintenance window without specific notice due to their frequent and routine nature.
