If you are using any custom BICs, be sure that you backup each custom BIC’s installation. In the simplest case, this would be the .jar file and the .config file in:
Windows: <EPX>/bin/agents/<BICmanager>
Copy these files into a separate location. Prior to importing any process flows which contain these custom BICs, replace the backup files in this directory:
Windows: <EPX>/bin/agents/<BICmanager>
