How to export from v1.0.5 and import into v1.2.7?

My current install is:
WebCalendar v1.0.5 (04 Mar 2007)

I want to upgrade to:
WebCalendar v1.2.7 (22 Feb 2013)

I have read this article:
http://webcalendar.cvs.sourceforge.net/viewvc/webcalendar/webcalendar/UPGRADING.html?pathrev=REL_1_2

However, I can't find help on how to move the calendar data itself. I have tried exporting from old version (ics and vcs), but both of them without success. The major problems seem to be timezones, description fields (getting cut off) and repeated activities.

Does anyone have experience from - or advice - on how to move calendar data from v1.0.5 to v1.2.7?
