Internal database error occured updating profile
This seemed to be a major issue to me until I performed the upgrade in my test lab.The statement above is correct for standalone mailbox servers, which is expected.Client Access servers are the first server role to update, and you should begin with the internet-facing site if you have multiple sites in your organization.For Client Access servers that are in a CAS Array you should remove some of the servers (eg half of them) from the load balancer configuration, upgrade them, re-add them to the load balancer, then repeat the process with the remaining Client Access servers in that load balanced array.Each of my test lab servers took between 20 and 30 minutes to upgrade, but your performance will no doubt vary.APIs can support the full range of CRUD operations.However for an Exchange 2010 Database Availability Group the upgrade process can be performed with no downtime following the normal process of moving active databases off DAG members while they are being updated.You can use the standard process as demonstrated here: However, be aware that once a database has been made active on an Exchange 2010 SP3 member of the DAG, it can't be made active on a pre-SP3 DAG member again.
The following table shows Eve’s implementation of CRUD via REST: Therefore, for sub-resource endpoints, only the documents satisfying the endpoint semantic will be deleted. When you do grant access to item endpoints, you can define up to two lookups, both defined with regexes.
As a result, when Mailbox servers are upgraded to Exchange 2010 SP3, the databases are upgraded to the Exchange 2010 SP3 version of the database schema…
…During the upgrade, the database is dismounted, and all mailboxes in that database are taken offline.
This means that you will need to roll through your entire DAG upgrading to Service Pack 3 to retain the full availability resilience your DAG is designed to provide.
For Hub Transport, Edge Transport, and Unified Messaging servers there are no special steps required other than to manage your upgrades in a way that aligns with whatever high availability you have in place or those server roles.If you are planning to upgrade your Exchange 2010 servers to SP3 you should be aware that there is an Active Directory schema update involved.If that is a concern for your environment, but you still want the bug fixes and security updates, you might consider sticking with Service Pack 2 and applying Update Rollup 6 instead.This differs from the standard behavior, whereas a delete operation on a collection enpoint will cause the deletion of all the documents in the collection. The first will be the primary endpoint and will match your database primary key structure (i.e., an Please Note According to REST principles resource items should only have one unique identifier.
