Ok, then follow this:
1) Prepare in GLPI the needed master data:
2) Prepare in Excel the master data mapping you need:
3) Extract master data from glpi tables to Excel (I did that with mySQL ODBC driver, creating a data source to mySQL server)
4) You need the detailed description of the glpi tables you need to fill in (for this I have an excel file, but I don't know how to send it to the forum):
5) Write mapping formulas or macros in Excel in order to map the old values to the one used in GLPI:
6) Migration steps:
Export data from you old system
fill in the sheets in Excel with your exported data (and don't forget to use the mapping and the master data values
then when Excel sheets seem ok, save them to unicode text files
use a tool to import the text files into mySQL (I used HeidiSQL: a free tool, very useful: http://www.heidisql.com/)
At each import, check in GLPI that everything is OK
7) Special case: attached documents (if you have some)
I have developed a small script in order to upload documents into tickets.
at your disposal for more info,
