Migrating Internet Service Monitoring agents from one system to another

You may want to migrate your agents from one system to another when you want to replace hardware or upgrade an operating system.

About this task

In the simplest scenario the new computer and old computer have the same hostname and IP address, and you install the same version of the Internet Service Monitoring agent. In this scenario, follow the steps below.

Procedure

Back up the Internet Service Monitoring agent on the old system. Back up the files in the following directories:
```
ISM_HOME/profiles/active
ISM_HOME/etc/rules 
ISM_HOME/etc/props
```
Optional: If you use the Objectserver, certificates, or datalogs, also back up the following directories:
```
ISM_HOME/datalogs
ISM_HOME/objectserver 
ISM_HOME/certificates
```
Shutdown the old system.
Install the same version of the Internet Service Monitoring agent on the new system.
Stop the Internet Service Monitoring agent on the new system.
Restore all content from the backup of the old system to the same directories on the new system.
Start the the Internet Service Monitoring agent on the new system.
In the Internet Service Monitoring Configuration UI in the Tivoli Enterprise Portal, check that the Internet Service Monitoring agent status is OK. If the agent is out of sync, resynchronize it by running Resync Agent.
In the Tivoli Enterprise Portal, check that the Internet Service Monitoring workspaces report the expected profiles and monitoring data.
