The cc:Mail upgrade wizard (end-user migration tool) is designed to work primarily with cc:Mail R2.x or R6.x clients and was designed to read certain information, such as a user's personal addresses and the location of the user's archive files, from .INI files residing on the workstation.
Unlike earlier versions of the cc:Mail client, the R8 client does not store information in .INI files. As a result, when users migrating from R8 run the upgrade wizard, they cannot migrate personal addresses and must browse for and select the location of archives (.CCA files) to migrate. This is being examined as a possible fix for a future release. R8 users can use the upgrade wizard to successfully migrate private mailing lists.
