When an upgrade to Control Manager 5.0 is unsuccessful, perform the following steps to roll back to your Control Manager 3.0/3.5 system.
To roll back to Control Manager 3.0/3.5:
Collect all Control Manager 3.0/3.5 backup files.
Install Control Manager 3.0/3.5. Refer to Control Manager 3.0 Getting Started Guide or the Control Manager 3.5 Installation Guide for instructions.
Use the backup authentication information
Select Keep existing Database and append new records option and specify where the backup Control Manager database is located
When you install Control Manager 3.0/3.5, setup generates a new public key. If you set the security level to high, the Control Manager agents registered to the original Control Manager 3.0/3.5 server re-import the public key to register to the new Control Manager server. Since a new public key is used, agents cannot match the original public key to the new one. The agents will not be able to register to the Control Manager server. To restore the original settings, reinstall all agents to re-register to the new Control Manager 3.0/3.5 server.
Copy and replace the Control Manager files with the Control Manager 3.0/3.5 backup files.
Apply Control Manager 3.0/3.5 service pack and hot fixes.
