Right. The critical thing is the possibility of a term for the frequency of the meeting that was omitted under AACR2 but is needed under RDA. (There may be other things, but that's the main one.) I believe that in most cases after this evaluation the main heading for a conference will be discovered to need no change under RDA; 008/10 and 040 $e can be fixed up, the 667 removed, and the 11X used in an RDA bib record.

From p. 4 of Summary of Programmatic Changes to the LC/NACO Authority File: What LC-PCC RDA Catalogers need to know,
1. Conference headings: any AACR2 authority record with a 111 field, and any authority record with a 110 field containing subfield $b whose text is present in a list of terms that mean "conference" in some fashion, will be labeled with a 667 field indicating that the 11X field must be reviewed before it can be used under RDA.
At Indiana we have noticed a couple of authority records that were flagged with the 667 note “THIS 1XX FIELD CANNOT BE USED UNDER RDA UNTIL THIS RECORD HAS BEEN REVIEWED AND/OR UPDATED” for which we cannot see any obvious reason for the flagging. One example is the AR for United Nations. $b General Assembly (n79007295). Can anyone enlighten me, please?
