I need to make changes in enumeration field by changing the Default Literal value to a new Value, but we have already defects created with some other default literal value. Does making changes in Default literal will impact the existing defects or not?

I need to make changes in enumeration field by changing the Default Literal value to a new Value, but we have already defects created with some other default literal value. Does making changes in Default literal will impact the existing defects or not?

The field Priority has three enum value:

1. Medium(Default Literal)

2. High

3. Low

Now we want to reassign the default literal by adding Unassigned value

1. Medium

2. High

3. Low

4. Unassigned(Default literal)

Will this change affect existing defects in RTC?
