Support for MySQL database would be removed in AssetExplorer from July 2017. 

AssetExplorer is built on top of ManageEngine's proprietary framework. This framework enables the flexibility to use the desired database. Currently, we are in the process of upgrading this framework for better stability and to include advanced features. The supported versions of the MySQL database are v4.1.18 and v5.1.0. Providing support for the older databases on the framework turns out to be a complex task and also affects the performance and scalability of the product.

The database being used can be identified by executing the file changedbserver.bat under <AE_home>/bin .

Thanks and regards,
