Browsing through the old /kde3.5/share/apps/config directory I've found the file containing the old identities (emailidentities). The account settings appear to be in the kmailrc file in the same directory. After copying this file, I checked the account settings. Copying the kmailrc file did the trick for the outgoing account settings, but the incoming (pop) account settings are still missing.
