How do you import user.dic to DWA?

We are wanting to move users to DWA 6.5.3 , as a first step we have upgraded users Notes client then mail template.It seems that user.dic is not imported to DWA mail file.

After some snooping I found a profile document $personaldictionary which has an attachement which I assume is the personal dictionary. I was hoping I could attach user.dic it it’s place. I detached the attachement in the $personaldictionary profile but it is not in clear text. It seems that user.dic is clear text with some control charaters???

Does anyone have any ideas of how to import user.dic ???
