Hello DanMr-5289 ,
Thanks for reaching out in the Microsoft Q&A!
Yes, you can activate Windows 11 Home with a Windows 10 Home key. Microsoft allows keys to be used interchangeably for activation. If your key is a retail key, it will activate Windows 11 Home when you sign in with your linked Microsoft account. If it is an OEM key, it should work on the same machine, but since you replaced the SSD, there might be an issue. However, it's worth trying the key during activation.
