I've attempted to upgrade from my existing 6.16 installation to the 7RC3 per the instructions. Cron job set up properly. Data Migration Config set up properly. Info inported from header.inc.php file in 6.16 installation looks good (selects proper database as shown in the 7 bx_migration_config table).
When I begin profiles data migration, it begins processing. Then I get Cron Error Reports which show that the migration tools are looking for tables in my 6.16 database which only exist in the 7 Database. Errors such as "Database Query Error in BxTempEmailblahblahblah.php , table 616_sys_localization_languages table does not exist".
This goes on for each table it is looking for and cannot find.
I'm sure this is a minor configuration error SOMEWHERE, but for the life of me, I cannot seem to locate it.
What I find in my database Profiles table for my 6.16 version once this process begins is that all of the profile ID's have been overwritten with new ID's starting with the last ID number in the table previously. So where I DID have IDs starting at 1 and ending at 4974, NOW I end up with IDs starting at 4975 and up.
This leads me to believe that the migration tool is attempting to both pull records from the old database AND to write the information back to the old database.
