Added a new Reserved Field Names section to the migration guide.
Clarified that certain field names (
__v
,salt
,hash
,file
, etc.) are reserved for internal use and will be sanitized from the config if used.Included additional reserved names specific to MongoDB, authentication-enabled collections, and upload-enabled collections.
Added a note recommending against using field names with an underscore (
_
) prefix, as they are reserved for internal columns and may cause conflicts in SQL and other contexts.Fixes #11159
