Use the Convert to Existing command in Control Studio to remove the selected composite and copy an existing composite in its place. If parameters are named the same in both composites and the parameters have been changed from the default value, the values of the existing composite's parameters are used.
In other words, if you have modified the default value for a parameter with the same name as a parameter in the new composite, the value will remain. Any parameter that has not been modified will receive the updated parameter value. For example, if you have modified the default value for parameter ABC, the value for ABC in the new composite will remain the same. Any parameter for which the default value has not been set will receive the new value from the composite as the default. Parameter ABC will be unaffected by parameter changes in the library.
If you convert an embedded composite to a linked composite, then the embedded composite will no longer exist in the database.
