[Dovecot] changing architecture

[Giuliano Gavazzi]

Dear all,

moving Maildirs from a PPC cpu to an Intel one (MacOS X to FreeBSD)  
not surprisingly I got:

Apr 23 12:08:50 drum dovecot: IMAP(x): Rebuilding index file /usr/home/ 
x/Maildir/dovecot.index: CPU architecture changed
Apr 23 12:08:52 drum dovecot: IMAP(x): Corrupted index cache file /usr/ 
home/x/Maildir/dovecot.index.cache: field header points outside file
Apr 23 12:09:01 drum dovecot: IMAP(x): fscking index file /usr/home/x/ 
Maildir/.Drafts/dovecot.index
Apr 23 12:09:01 drum dovecot: IMAP(x): Corrupted transaction log file / 
usr/home/x/Maildir/.Drafts/dovecot.index.log: file size shrank
Apr 23 12:09:01 drum dovecot: IMAP(x): fscking index file /usr/home/x/ 
Maildir/.Posta indesiderata/dovecot.index
Apr 23 12:09:01 drum dovecot: IMAP(x): Corrupted transaction log file / 
usr/home/x/Maildir/.Posta indesiderata/dovecot.index.log: file size  
shrank

I suppose owed to the endianness change. Can I thus just remove those  
dovecot.index files, including dovecot.index.cache and  
dovecot.index.cache.log?
I know I could let dovecot do it, but as the cache files in particular  
are quite large, it would save me band simply not transferring them  
with rsync from the old server.

thanks
Giuliano
