IMPLEMENTING EXCHANGE 2016 CUMULATIVE UPDATES The procedure for installation is as shown below: Conduct the Active Directory schema amendments and updates. This is conducted once for the complete Active Directory environment. You do not require repeating this for every server being upgraded. Upgrade servers. For every server in turn: · Keep the server into maintenance mode. · Install the update. · Conduct testing. · Pull the server out of maintenance mode. Conduct post-installation assignments: · Rebalance database availability groups. · Restore customizations. · Perform a health examination of the environment. ACTIVE DIRECTORY SCHEMA AMENDMENTS AND UPDATES · Most cumulative updates are going to include the Active Directory schema alterations, as well as other updates like, changed to RBAC roles. · In few cases, the existence of changes is going to depend on which previous CU you’re upgrading from. Therefore as a general rule you should plan for AD schema alterations and updates to happen. · The AD preparation tasks can be executed in advance of your server upgrades, or they can be permitted to execute automatically as part of the primary server upgrade process. · In any case, Enterprise Admins and Schema Admins rights are going to be required. And in case you’re executing the update from an Exchange server, the RSAT-ADDS feature should be installed. · Prior of deploying the schema update pursue the steps given by Michael B Smith to retrieve the present Exchange schema version, such that you can compare & estimate it before and after the AD preparation procedure have been finished to verify that the schema update was applied. · Execute setup.exe /PrepareSchema /IAcceptExchangeServerLicenseTerms (needs Enterprise Admins and Schema Admins permissions, and should be conducted in the same AD Site as the Schema Master on a server with the RSAT-ADDS-Tools properties installed – the Schema Master itself may meet these requisitions) · Execute setup.exe /PrepareAD /IAcceptExchangeServerLicenseTerms · Execute setup.exe /PrepareDomain /IAcceptExchangeServerLicenseTerms in every domain in your forest which includes Exchange servers or mailboxes. In case you have a single domain, the earlier step has already performed this for you. When the Active Directory amendments have been applied on every server CONDUCT A HEALTH CHECK OF SERVERS
