Deleting data from HDD after migrating the operating system to SSD?

Question

I installed a new SSD just recently, and decided to migrate my OS onto it from my old HDD after performing a clean reset, is it alright for me to delete all of my old data from the HDD after migrating OS? Will there be any issues?
Here's a screenshot of my disk managment ("disk 0" is the HDD, and "disk 1" is the ssd).

Answer 1

Looks Ok, disk 1 has a boot and system partition. You could try unplugging old disk for a test.

Hello,

Thanks for reaching out.

If you are able to boot with your new and all DATA have been copied to new one. Then you can remove old hdd.

Also for added safety you can remove drive letter of old hdd volumes so it won't show in My computer.

Thank you,
