I followed the same route as Mauricio.

1. I installed H5 from scratch with webmail-install and added the 
configuration step by step until the H5 installation worked like expected. 
Some settings can be copied from H3, some cannot. But the H3 config is a
good reference, in order to make sure you do not forget someting.

2. The data: 
2.1. I copied my running H3 into a virtual machine, upgraded that to the 
latest webmail 1.2 aka H3.3 
release, see http://www.horde.org/apps/horde/docs/UPGRADING. There is no 
need that the installation or features all work, it's all about the 
database. In fact, some features did _not_ worked on this intermediate 
machine, but the data were severe.

2.2 I copied the H5 install from step 1 into yet another virtual machine, 
imported the H3 database, re-ran the webmail-install script, which 
migrated the database, then finished with: echo y | kronolith-convert-to-utc

3. Lastly, I replaced the database of the H5 machine of step 1 with the 
one of step 2.2.

As you see, I did not upgrade the H3 inplace.
