[Dovecot] Move from 1.0.rc29 to 1.1.7?

[Peter Lindgren]

Hello!
I am moving my mail from the old server with 1.0.rc29 to a brand new 
server with 1.1.7. I use Maildir in both servers. A few questions:

1) The new server has another name, can I just copy the mail files 
as-is, will the server name in the file names matter?

2) The new server has a different architecture and different endian, so 
I plan not to copy the index and cache files; they seem to have become 
broken from time to time in the old server anyway. Dovecot will also 
re-create them when needed. Ok?

3) 1.0.rc29 did not store the message size in the file name as later 
versions. When will Dovecot do the check and rename the files to include 
the message size? There are some folders with quite large number of 
messages, the largest is some 45,000 messages.

TIA,
/Peter
