One-button migration did not copy filters, calendar events, deleted messages.
All column customization and order criteria are lost. There is enough for me
not to migrate at all. Currently I have no time and/or fun for inspecting and
fixing every folder manually.
Step-by-step migration with creating empty store, then replicating folders does
not copy calendar events nor deleted messages. Filters are copied, but... Look
yourself at http://www.jbw.pl/file/Scribe/b24_filters_v2.png (before) and
I'm pretty sure that Trash should be migrated intact. There is no reason to
make it empty without user's agreement. Trying to copy or move Trash content
with drag/drop from old store to new one makes program crash:
Surprisingly, can copy Trash by selecting all messages, then Copy/Paste them.
IMO migration should replicate each entry of each folder from original store,
as well as column presence and order, sorting criteria. If some elements could
not be copied for important reason, it should be clearly reported.
Perhaps I could fix my folders and begin to use v3 store from now, but decided
to stay with v2 to be your "voice of conscience" until everything will work
