How to upgrade a management server - upgrading a distributed management group
When you upgrade a distributed management group to to System Center 2016 - Operations Manager or version 1801, you start by upgrading each of the management servers in your management group. There are a number of pre-upgrade tasks that you must perform first. For more information, see Pre-Upgrade Tasks When Upgrading to System Center Operations Manager.
Between the time that you upgrade the management servers and upgrade the agents, you might experience Application Platform Monitoring (APM)-related event log entries on the agent-managed servers. These event log entries might occur on agent-managed servers that are not APM-enabled. These event log entries will be resolved when you complete the upgrade of the agents. You might have to restart the health service after the agent is upgraded in order to clear the events.
Because the ACS Collector server must be on same machine as a management server, we recommend you perform the steps described in How to Upgrade an ACS Collector along with the upgrade of the management server on which ACS resides.
When upgrading multiple management servers in a distributed management group, you must wait to start upgrade of additional management servers until after setup on the first management server completes. Failing to do so can cause a SQL update script that runs early in the set up process to run on multiple management servers and result in database issues. This SQL update script only needs to run on the initial management server being upgraded.
When upgrading multiple management servers in a distributed management group, sequence the upgrades in a manner that best suits your business needs. Upgrade all management servers in the distributed management group as soon as possible after the initial management server is upgraded to verify that your upgraded environment is healthy.

Upgrading a management server is just one phase of the distributed upgrade process. Upgrade is not completed until you have upgraded all of the other features in your management group. The next step is to upgrade any gateways. See How to Upgrade a Gateway Server for more information.

Open a Command Prompt window by using the Run as Administrator option.
Change the path to where the Operations Manager setup.exe file is located, and run the following command.

After you have upgraded all of the management servers in your management group, you should upgrade gateway servers, and then upgrade any stand-alone Operations consoles.
