Where can I see each country options? Brazil has 4 country options: brazil, brazil direct, brazil-922, brazil-anatel. What?????

Morning,

After upgrade one x86 system with v6rc12 it creates a file named um-before-migration.tar with 2 files inside: logsql.umb and mainsql.umb. Just delete it?

My backup/email script just works for 4.4 after marking sensitive policy. It was ok for 4.3 without sensitive option.
