Importing MySQL tables from other database in live site with mysqldump can cause trouble?
If they are on the same server, I'd do the table 'copy/replicate' this way:

CREATE TABLE detinationDB.new_table like sourceDB.TblName;
INSERT INTO detinationDB.new_table SELECT * FROM sourceDB.TblName;
RENAME TABLE detinationDB.TblName TO detinationDB.DropMe, detinationDB.new_table TO detinationDB.TblName;
DROP TABLE detinationDB.DropMe;


This way, you avoid dropping the old table before making sure the new table is there. 

This is good if you intend to keep booth DBs on the same server.
