basically you can't merge big amount of pages automatically. you have to check merging result anyway.

list of pages, u need database dumps:
 * 1) open 1st database, start database scanner, select namespaces, then generate and save list.
 * 2) open 2nd database, generate list as above and filter it by previous generated list (operation-intersection).
 * result: titles in both databases.

also, awb can save pages on your hd in order to merge them, but it will kinda tricky: you'll have to define external processing program (batch script is enough) which will replace page content from 1st database to 2nd.
