Are there dynamic pages connected to the collection? If so, convert them to regular pages or delete the pages unless you plan to connect a different collection. Visitors to your live site will encounter a 500 error when attempting to view dynamic pages associated with the deleted collection. Are any datasets connected to this collection? Make sure to remove any connected dataset filters that are in use. This includes datasets set to filter by reference field or by dataset. If your filter settings are unmatched, the dataset will be empty.  Is this collection referenced in another collection? If the collection is referenced elsewhere, make sure to remove the reference by either updating it to a different collection, modifying the field type, or deleting the reference field.
