We used that for our 150k user infrastructure and had no IO headaches at all. It was a good moment to update distribution, filesystems, hardware, .... as well. I tested conversion speed from 2.3 to 2.4 on about 100 mailboxes and it was pretty obvious that touching all our mailboxes in one shot is clearly impossible without unreasonable downtime.
