Problem:

When additional values are added to a custom enumerated field will this affect existing objects which use the custom field?

Resolution:

There will be no detrimental effect from adding values to an existing custom enumerated field. Existing objects which make use of the field will maintain their current values for the field and the additional values will be available to be selected. This is possible because each entry in an enumerated custom field is identified by a unique ID. Therefore when a new entry is added to the list, the current value held by each object will remain unchanged because the ID number and its corresponding value remain unchanged.
