Error
There seems to be one or more errors with the database configuration information that you supplied:

The MyBB 1.6 database could not be found in 'u7414307_xb'. Please ensure MyBB 1.6 exists at this database and with this table prefix.
Once the above are corrected, continue with the conversion.

Please help

It looks like that database info you entered doesn't match on the server or your web host. If you're using a shared host, make sure you prepended the right global database prefix to your configuration, because some hosts using cPanel employ that to eliminate DB name conflicts.

One database is old. And one is on 1.6

You will probably need to upgrade the old database to 1.6 before merging them
