How to get the demo's results?

[xy815661276]

I used the tools provided by you and migrated redis according to the operation in the video, but I used redis to set the key to random and the value to 123456, but after the migration, I got nil for get random.
The environment I use is the same as in the video, the system in aws, and the mirroring and configuration are the same. My local arm64 virtual machine and x86-64 virtual machine have the same result. I don't know what went wrong, can you help me, thank you
