Migration tool not transferring databases

During the migration process, almost at the end of the process, the tool starts to migrate databases and then errors occur:
On the display:
ERROR 1049 (42000): Unknown database '********'t
ERROR 1049 (42000): Unknown database '********'t
ERROR 1049 (42000): Unknown database '********'

Hi Till, thank you very much for the prompt reply.
You were right, in /usr/local/ispconfig/server/lib/mysql_clientdb.conf I had the wrong password. But this does not solve the issue completely, the tool succeeds to import about 50 databases and refuses to import the remaining ~80 db with the same output in the log.
When tried to pass the command:
gunzip -c /tmp/migrate-import-tmp.sql.gz | mysql --max_allowed_packet=1G -h 'localhost' -D c1eltransport -u 'root' -p'******'
MySQL respond with ERROR 1049 unknown database which was expected.
All the databases from the old server exist in ISPConfig web interface but are not created in MySQL.

 

Thank you very much, Till ! Everything passed smoothly, the new server is online.
