hello,
I found the solution.
looking at the databases, there are 5 fields on the fog 1.2.0 base and there are 9 fields for version 1.5.9.
so the hots don’t appear.
by importing the database on the new server and importing the csv host everything is ok.
the export of the csv on the 1.2.0 server was with the separator ,
I reworked the file with free office to put it in ;
it works.
I leave the solution here for old fogs who want to migrate to a new machine 🙂
