There is no step by step guide for the Groupware suites, but you should follow general instructions here:

http://www.horde.org/apps/horde/docs/UPGRADING#general-instructions
http://www.horde.org/apps/horde/docs/UPGRADING#upgrading-horde-from-3-3-x-to-4-x
http://www.horde.org/apps/webmail/docs/INSTALL

Basically you 1) backup, 2) just install new version and 3) then use the same data backend which will be adapted for the new version.
