KMail in 8.2 import folders from KMail in 8.1

Dear List, Forgive me if this has been answered. I have bone a fresh install of 8.2 on an existing PC that had 8.1 installed. The new install is on a new HD and the old HD has been setup as DATA1. Now I'm trying to get the new KMail 1.5.1 on KDE 3.1.1 to import my old folders from the 8.1 KDE 3.0.5 KMail. The new KMail has an 'import tool' but the choices do NOT include importing from a KMail source. What am I missing. I assume that I could move the sub-dir Mail from my old {home} dir but I know how assuming can hurt you. The KMail Handbook and FAQ do not hepl. Thanks! .............. PeterB
