Migration Thunderbird de 3.1 à 10.0

Des façons de faire :

1. http://wiki.sogo.nu/TB-upgrade-3-to-10

2. • [SOGo] Migrationpath 3.x -> 10.x ?
     
     What we have done is:
     
         * Un-install lightning, connector, integrator
         * remove "calendar-data" folder from user's profile
         * install TB 10 ESR over 3.1 and configure any options (proxy, disable updates, etc)
         * install lightning, connector, and integrator
     
     We do this, so the user gets a fresh copy of the calendar cache, we have noticed that it is smaller than in the 3.1.x versions - it does take some time to initially build the cache but we feel it's better and could present less problems down the road with corrupt cache files...
