With the popularization of Web applications and the emergence of cloud computing technology, database management and storage has evolved from PC to Web-based, even to cloud-based services as well. Also, with big data applications in cloud computing, more many organizations will eventually move their data from Web applications to a cloud-based environment. Except the cloud migration method, the cloud platform must provide an automatic tool in application and data migration for easy implementation. The existing Sqoop data migration tool requires users to be familiar with existing migration commands or move the data manually to a cloud-based database. Hence, the purpose of this paper is to design a new automatic data migration tool named MSCH using the migration of MySQL to HBase as an example to improve on the processing performance of Sqoop. After simulations, the experimental results show that the MSCH migration tool was 33 %, 25 %, and 15 % faster than Sqoop in terms of number of entries. CPU utilization during migration was also reduced by 35 %, 43 %, and 33 %, while memory usage was reduced by 90 %, 72 %, and 74 %, proving that the MSCH data migration tool shortens data migration time and lowers the load on computing resources to enhance the performance in data migration under cloud-based environment. Further studies will be conducted to determine the migration accuracy ratio of MSCH migration tools and Sqoop.
