I need to migrate existing 12c OMS host only from smaller resource host to large resource host with the same repository database. From all the docs I have understood to follow below steps:
1.Shutdown OMS on existing host
2.Install OMS on new host with connection details to the same repository db
3.Migrate all agents to point to new OMS by modifying the <AGENT_HOME>/sysman/emd.properties file
If anybody has performed similar OMS migration please let me know if this is the right approach or I am missing any steps?
I can go away with the existing SYSMAN schema but I would prefer to keep the existing SYSMAN schema in-tact. If I can what steps I need to follow and what steps to follow if I have to drop existing SYSMAN schema?
7.In the Cloud Control console, locate the 'WebLogic Domain' target for the Cloud Control Domain. Go to 'Monitoring Credentials' and update the adminserver host to host B. Then do a Refresh Weblogic Domain to reconfigure the domain with new hosts.
I tried to explore the "monitoring credentials" option but it seems to be something different but not sure I went to the Weblogic console where it has the option of lock&edit and change the admin server host. Do you know am I at the right place?
Just want to confirm one thing, if I simply drop the sysman schema shutdown the current oms. Then can I point the existing repository db to the new OMS, or do I need to take care of some additional steps?
