Yes, this might be a bit painful for the early adopters. Is there any sort of magic number or similar where slapd could bail out "sorry, please slapindex" if given a RE23 format database? Then at least the FAQ-O-Matic could point out "use 2.4.6 slapcat then upgrade again" or some other concrete procedure.
In this case, all you'd need is to run "slapindex -qt" to recreate the relevant indices. (Whether that's actually faster than slapcat/slapadd, I don't really know. Historically it's been pretty slow...)
I guess we can detect an old format index when it gets referenced, but currently we don't reference them until an actual search operation comes along. I.e., it's not something we would normally check at startup time, and it would be pretty awkward at runtime.
On the other hand we could even let the runtime indexer task recreate the indexes on the fly when such an old index is discovered. ;-)
