This article outlines the step-by-step procedure for upgrading your MySQL database from version 5.7 to 8.0 to ensure the seamless transition of your OvalEdge application. This upgrade is essential for maintaining compatibility and taking advantage of the latest features and improvements in MySQL 8.0.

Please follow the instructions below to perform a successful upgrade:
