DATA ELEVATOR MYSQL

The data elevator mysql is an easy to use and very flexible utility for migrating data sources based on the NPM module data elevator. The only difference is that data elevator mysql stores its current migration level in a mysql database.

Storing the current migration level in a database brings advantages when a project shares its data source with multiple running instances of a project. For example when multiple developers working with one database or the project runs on multiple servers.

QUICKSTART

npm install data-elevator-mysql

STEP 2: Construct a new data elevator for the project.

STEP 5: Move the elevator to migrate data.

node ./data-elevator/elevator move top
