Hello.

I see dovecot 1.1 will be release very soon. I'm thinking about a migration from my 1.0.14. The migration job will be hard/long?

It shouldn't require more than possibly changing some configuration settings explained in the wiki page. Usually not even that.

I see in http://wiki.dovecot.org/Upgrading/1.1 that dovecot-uidlist file are in a new format. It will be problem for Courier (pop/imap) upgrades? (today, I often upgrade old mailboxes in Courier to my Dovecot server).

No. v1.1 (and future versions) can still read the old format just fine. You just can't go easily back to Courier or Dovecot versions older than v1.0.2.
