[Dovecot] dovecot upgrade

Hi, I'm currently using Dovecot version 1.0 and I want to update it to the latest version. I know from version .99 to version 1.0 I had to change a few things on the dovecot config.

When compiling the latest stable version should I just be able to use the same config I'm using for version 1.0 without making any changes ?

Thank you Paul
