To create your Test environment:

1. Go to the Site Dashboard.

2. Click the Test tab, then click Create environment to create your Test environment.

   

   This takes a few moments.

To create your Live environment:

1. Go to the Site Dashboard.

2. Click the Live tab.

Review Troubleshooting or contact Support if the migration is unsuccessful. Include a link to the Site Dashboard and any details you can provide, such as where you are migrating the site from.
