Upgrade Mail server and webmail

[Hai DangB]

Hi everydoby
I'm newbie using Plesk control panel.
I have a dedicated server with Windows server 2003, Plesk 9.2, Mail Enable Standar, Horde Webmail.
Today I realized that Mail Enable Standar not good. Webmail does not support save the email sent (sent mail folder).

Can I upgrade to Mail Enable Pro (still keep customer information: user, password, and other options, ..). Or I can switch to using Merak not affect to active customers?
Thanks
