KMail Update

G'day Trinity Users, At last I've found a tuit ( a round one) :-) Upgrading from TDE 3.5.11 to Trinity R14.0.2. So far, I've got Ubuntu 14.04.4 with Trinity R14.0.2 on another computer. My yellow-streak compells me to leave the working TDE 3.5.11 system alone until the new box is properly configured. My main problem is transferring KMail settings and mailboxes to the new system, so my questions are .... 1. Is it just a simple copy of the files from the old to the new systems? 2. If this is possible, which files need to be copied? From where to where? (Seems that paths and directories are very different on the two systems). FWIW. I tried searching the list archives but my search-foo is rather low just now, but I found some references that suggest that what I want to do is actually doable. Thanks in antic, Glen PS. If anyone is interested, the "new" system is an Aldi Akoya E4214 which is not as yet well supported by Linux distros but eventually got WiFi working with a custom compiled driver. G.
