[Evolution] Migrating data from Evolution 2.28 to 3.6

[Peter Meyer <petermeyer69 gmail com>]

All:

I am attempting to migrate my evolution mail data from 2.28 (Ubuntu 
10.04) to 3.6 (Ubuntu 12.10).

Is there a way to migrate the data?  Can someone please point me to 
where the files are located in each release and any suggestions on 
migration strategies.  I've tried using the backup/restore and this does 
not work.

Thoughts?

Peter
