Validate V1 core devices can run V2 software
The Amazon IoT Greengrass Core software v2.x has different requirements than the Amazon IoT Greengrass Core software v1.x. Before you
upgrade V1 core devices to V2, review the device
requirements for Amazon IoT Greengrass V2. Amazon IoT Greengrass V2 doesn't currently support migration for custom
Linux-based systems using the Yocto
Project.
You can use Amazon IoT Device Tester (IDT) for
Amazon IoT Greengrass V2 to validate that devices meet the requirements to run the Amazon IoT Greengrass Core software v2.x.
IDT is a downloadable testing framework that runs on your host computer and connects to devices
to be validated. Follow instructions to use
IDT to run the Amazon IoT Greengrass qualification suite. When you configure IDT, you can choose to validate
whether devices support optional features, such as Docker, machine learning (ML), data stream
management, and hardware security integration.
If IDT reports V2 test failures or errors for a V1 core device, you can't upgrade that
device from V1 to V2.
