Migrating to Web Application
To migrate to the web application, you can do it through a backup <../web/migrating_to_web> or through the “Connection” mechanism.
In short: you need to create an empty project in the web application, click “Connect” in Unity’s Inspector window, and specify that you want to upload data to the web application.
Migration with Connection
Be sure to back up your local data before making any connections.
In the Web Application: on the Home screen, click on “Create Project”
Specify the project name, tags, and script language
Click the “Create” button
In the Unity Editor: select your game data file in the “Project” window
In the “Inspector” window, click “Connect”
In the dialog that opens, click on the “Profile -> API Keys” link
In the Web Application: a page of your profile on the “API Keys” management page should have opened in your browser
Click “Create API Key…” button
Fill in the name and expiration time, then click the “Create” button
Click the “Copy” button in the list of keys next to the newly created key labeled “New!”
In the Unity Editor: paste the “API Key” into the corresponding field in the window
Check the “Upload local data…” checkbox, it is only available when the selected “Project” is empty and does not contain any data.
Click the “Upload” button”
