“EXIT” – Export Across Instances Tool
This is a simple and self-contained tool that helps automate the process of exporting your magazine subscriptions from one instance to another, provided you have accounts on both.
Could also be used to copy subscriptions from one named account to another named account on the same instance, or to back them up for later.
