My view would be to press on with the new - we took that approach for our main stock with RDA, our catalogue we'd accept would be hybrid so it wasn't an issue.
Is the collection a finite collection in that once you're done, you're done? If that's the case then (playing Devil's advocate here) why move to RDA? With us, even though we're using RDA for the main cataloguing, we're still using DCRM(B) for the special collections stuff...

It has been interesting to read of some people using RDA already for rare books. The situation I am in is that the catalogue I am working on creating has been about 10 years in the making and has a good consistency of abiding by DCRM rules. Although it would be easier to adjust authority entries such as changing 'fl.' to 'active' etc., it would be much harder to justify modifying all of the free text entries in the 27,000 records to date. My primary purpose is to press on with new cataloguing, not going back over old ground. Have people reached different conclusions?
