Taking precautions for mode transitions
Ensure that all nodes to be transitioned are running the same version of Network OS. Logical chassis cluster mode is supported starting with Network OS release 4.0.0
If you are merging multiple global configuration files to create one new global configuration file, be sure that the same entity name does not exist in the merged file. For example, if mac access-list extended test1 contains the entries shown in the following "Node 1 global configuration" and "Node 2 global configuration", when you merge the files you can rename mac access-list extended test1 from Node 2 to mac access-list extended test2 , as shown in the "Combined global configuration."
