Download the new Grid control software, copy the downloaded files to the host where grid control is currently installed and unzip the two files.
Shutdown the OMS with
emctl stop omsIt is important to stop it without the "-all" option. If the OMS is stopped with "-all" option then following warning will appear during the upgrade.
emctl config emkey -copy_to_repos -sysman_pwd gridb321 Oracle Enterprise Manager 11g Release 1 Grid Control Copyright (c) 1996, 2010 Oracle Corporation. All rights reserved. The EMKey has been copied to the Management Repository. This operation will cause the EMKey to become unsecure. After the required operation has been completed, secure the EMKey by running "emctl config emkey -remove_from_repos".After this stop the oms again (without the -all option) and rerun the installer.
There other warnings and errors where some would allow to continue whereas others would require some steps to correct these warnings.

12c grid control Home page.
It could be seen that agents from exisiting hosts have already started communicating with new OMS.
12c's new ASH Analytics page
Last step is to deinstall the old agents and OMS.
To deinstall the agents from local and remote hosts including RAC follow the agent deinstall post or How to Remove the 11.1.0.1.0 Grid Control Management Agent with the Silent Method [ID 1068036.1].
For OMS use How to Deinstall 11g Grid Control Components in Graphical Mode
More inforation is available from Enterprise Manager Grid Control Advanced Installation and Configuration Guide
To enable/disable the auto start of any agent
chkconfig gcstartup on/off chkconfig --list | grep gcstartup gcstartup 0:off 1:off 2:on 3:on 4:on 5:on 6:off
