[sympa-fr] problème upgrade base mysql sympa

[Anne-Marie Philippon <adresse@cachée>]

Bonjour
Je viens d'installer un nouveau serveur sympa en version 6.1.5
Après avoir récupéré la base sympa installée sur une version 5.2.4, je n'arrive pas à upgrader ma base:

Voici ce que j'obtiens:
/usr/sbin/sympa.pl --upgrade --from=5.2.4 --to=6.1.5

err Upgrade::probe_db() Could not set field 'email_user' as PRIMARY KEY, table'user_table'.
Database sympa defined in sympa.conf has not the right structure or is unreachable. verify db_xxx parameters in sympa.conf

Comment s'en sortir?
Les paramètres db_... de sympa.conf sont identiques à ceux de la version 5.2.4
Si je supprime une des 2 entrées  adresse@cachée, je tombe sur la suivante, etc

Merci de m'aider
