They are different terms for the same thing. Both are the number of pages
of memory that will be allocated for the DbCache. Caching size and
behavior are different for Classic and Superserver.

Back it up with gbak and restore it with a new page_size. Don't use the
-r[estore] switch!! use -c[reate] and retain the old db until you're ready
to kick over to the new.

The "rules" (such as they are) haven't changed. The optimizer has changed
quite significantly. So keep to the existing guidelines and expect
improvements.
