Now I want to build a new system on CentOS 6.4 64bit with postfix, dovecot and migrate all user accounts and their emails.
I assume you've already reviewed the migration pages on the wiki?

My only advice would be to consider dropping the INBOX. prefix - this has some significant affects for the migration but will prevent headaches from clients that don't handle namespaces correctly (like all iOS devices.) Or, maybe add a second hidden namespace for INBOX. compatibility so existing clients that are hard coded hopefully wont trip up on themselves too bad.
