The sandbox preview window for Summer ’21 begins May 7, 2021. You must have an active sandbox on a preview instance by May 6, 2021 (the day before sandbox preview) to take advantage of the preview.

Are you refreshing a sandbox - how do you get data into it?

Join us to find out how Mike Eagan tackled this issue with Data Parrot

As a Salesforce AppExchange Partner (ISV), Data Parrot was created to solve the sandbox problem. It enables Admins, Developers and QA Users to copy complete sets of related data from any source to any target within a Salesforce production organization. Auto-discover all available sandboxes, build and copy data sets via a simple point and click query builder, include or exclude objects and managed packages and apply field masks to sensitive data fields. Data Parrot helps to increase the quality and accuracy of continuous development and deployment and decrease the development life-cycle timelines.
