[horde] Migration from 3.1.3 to 5.x

[Nicolas C.]

Hello,

I'm using Horde 3.1.3 with Imp, Turba, Kronolith and Ingo and I'm 
planning to upgrade to 5.x, this is what I had in mind :


  - Install a test version 3.3.13 (just the framework)
  - Import the 3.1.3 database in the 3.3.13 installation
  - Apply patchs "3.1_to_3.2.mysql.sql", 
"2008-08-29_fix_mdb2_sequences.php" and "3.3_to_3.3.5.sql"
  - Install a test version 5.x with Imp & co
  - Import the patched 3.x database in the 5.x installation
  - Execute "horde-db-migrate" (?)

Is it the right way to do it?

So far, it's not starting very well because I can't make a "new" 3.3.13 
installation from tarball to work. No red light in the "test.php", no 
error in Apache logs, all I see is what looks like an infinite 
redirection (and a lot of session files in /varlib/php5) :

I'm using a Debian Squeeze server with a Pear installation in 
/var/www/horde3 and a MySQL database named "horde3".

Any help would be appreciated.

Regards,

Nicolas
