Actually it is not that easy to install a new H4 out of pear these
days. You can savely upgrade to Horde 5.

Don't forget: Horde 3 uses local timezone instead of UTC by default
AND Horde 3 does use local charset (mostly latin1) instead of UTF8.
For porting to Horde 4 or 5,

Either set the database configuration and kronolith settings right or
convert your data before.

You also should not copy-and-paste prefs and hooks without looking. A
lot of prefs have been renamed or even disappeared. The Hooks format
has changed.
