Mysql Replication backup and restoration failed multipal time

I tried restoring MySQL backup several time but unfortunately it gets failed by some or the new reason.

I have 2 host Master & Slave with below details.

Server1_Master
os-centos6.7
mysql- 5.6.28-2.el6

Server2_Slave
os- centos6.6
mysql- 5.5.41

Engine: innodb (on both host)

Below are the respected step used by me.

Master Backup

mysqldump -uroot -p --skip-lock-tables --single-transaction --flush-logs --hex-blob --master-data=2 -A > ~/dump.sql

Restoring mysql on slave

mysql -u root -p < /location/dump.sql

CHANGE MASTER TO MASTER_HOST='<>',MASTER_USER='replicant',MASTER_PASSWORD='<>', MASTER_LOG_FILE='<>', MASTER_LOG_POS=<>;

START SLAVE;

Now the new error which we am getting after server hrs of restoration is below

"ERROR 1449 (HY000) at line 150536: The user specified as a definer ('lipl_ga_app'@'%') does not exist "

Please let me know the best way to start new replication.
