I really, really, hope this isn't really a major redo of The Old. I thought that it was the Cashen that would be remodelled?
Martin Hawtree has remodelled a lot of the classic Irish courses in recent years: Dooks, Lahinch, Royal Dublin, Belvoir Park, The Island, Portmarnock. Some of this was quite major work (a lot of new greens at Royal Dublin for example).
I haven't seen any of the new work so can't comment on whether I like it or not...I hope they haven't gone too far.
