Compatibility Mode allows users with previous versions of the Control-M client to connect to the latest version of Control-M/EM server in addition to the upgraded Control-M clients. However, when Compatibility Mode is on, new features are disabled in upgraded Control-M clients. This ensures system integrity during the transition to a higher version. After Compatibility Mode is turned off, the new features are enabled in the upgraded Control-M clients and older clients are disconnected. Users that have not upgraded their Control-M clients cannot log in.
The following table lists the features that are disabled in Control-M clients after you have upgraded and compatibility mode is on.
| Source version | Target version | Disabled features | 
|---|---|---|
| 9.0.00.xxx | 9.0.21 | 
 | 
| 9.0.18.XXX | 9.0.21 |
