Evenrefs on person are still broken as I do not know how to parse 
something which is not handled yet ...  :(

I am happy to update their old GRAMPS XML to the latest release if they are happy to send it to me privately.

I agree with Gary, the only safety way is to use Gramps-2.x and 
importing old databases. http://www.gramps-project.org/bugs/view.php?id=2206


At first glance, here what changed on GRAMPS XML since Gramps-1.0 :


1. The XML header :
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE database PUBLIC "-//GRAMPS//DTD GRAMPS XML 1.2.0//EN"
"http://gramps-project.org/xml/1.2.0/grampsxml.dtd">
<database xmlns="http://gramps-project.org/xml/1.2.0/">
previously was :
<?xml version="1.0" encoding="iso-8859-1"?>
< <!DOCTYPE database SYSTEM "gramps.dtd" []>
< <database>

(non-ASCII characters ???)

2. Attribute on HOME person
<people home=
previously was :
<people default=

3.
<person id="I0">
    <event type="Death">
       <dateval val="1945-09-29"/>
       <place ref="P1"/>
is now, something like :
<person id="I0">
   <eventref hlink="_a701e8fe8ea06c7fba4" role="Primary"/>
</person>
<event id="E0000" handle="_a701e8fe8ea06c7fba4">
   <type>Death</type>
   <dateval val="1945-09-29"/>
   <place hlink="_HINT6DP8JGGL0KKB8J"/>


* Maybe Testing :

==date parser==
Date was just a textual value on Gramps-1.0.x.
How this will be parsed by current date handler ?

==number of characters on fields==
Does 2.x introduces limitations ?


Also, handle and hlink attributes will be added on first import (BSDDB 
references). Sources, places, objects seems to be the same, 2.x moved 
event as a primary object, was the major DB upgrade.
