Hi Ntozier:i tried to update from 1.6ST to 1.9.1 several times, clean installations with my db and always get the error:DB Error #1054and: Upgrader Error------------------------------------If i install 1.6ST with a clean database and the upgrade to 1.9.1 i got no problems.Also i have zero attachments in folders.

Hey reyhykary podrias compartir tus archivos ya traducidos?

I found this in another thread:1.6ST (Current Version) => 1.7.0 => 1.7.7 => 1.8.0.4 => 1.8.1.2i will test it and post results

Update:I'm still getting the error with the database.But i'm thinking that maybe i could only export/restore the tickets table from the database and everything else i will rebuild it.I'm very interested in keeping my old tickets

Ok, I uninstall everything and start again with 1.6 ST , then upgrade to 1.7 and then to 1.91no problem with that.BUT! if i install 1.6 ST and restore my database and then try to upgrade to 1.7 the system show me the same error,this makes me belive there is a "situation" with the database builded for the 1.6 ST version. so we need to migrate that database to 1.7 and the upgrade to 1.9, anyone know if its posible to migrate database from 1.6 to 1.7 or directly to 1.9?
