Trend Micro recommends a phased upgrade for large, single-server Control Manager 5.0/5.5 networks. This is essential for multiple-server networks. This method offers a more structured approach to migrating your system, and follows these guidelines:
- Start migration on systems with the least impact on the existing network, and then proceed to the systems with progressively greater impact.
Upgrade the old network in well-planned stages, rather than all at once.
This will simplify any troubleshooting that may be required.
Phased upgrade involves the following steps:
- Install TMCM 6.0 on a server that does not have any previous TMCM version installed (preferably without any managed products).
Run the AgentMigrateTool.exe on the TMCM 6.0 server.
Use the Control Manager agent installation together with the Agent Migration tool to plan the upgrade of agents on existing TMCM networks. The Agent Migration tool can generate a list of servers with TMCM agents. Doing so eliminates the need to manually select the agent servers.
