Is secure to do something as:

UPDATE RDB$RELATION_FIELDS
SET RDB$FIELD_SOURCE='NEW_DOMAIN_NAME'
WHERE (RDB$FIELD_NAME='FIELD_NAME' AND
(RDB$RELATION_NAME='TABLE_NAME')

It depends what you call "easy". Referential integrity protects
references. That creates dependencies. So start at the bottom of the
dependency chain. You can put the dependencies back once you have changed
