Domain migration, need to reactivate

Hi,
We have migrated aromextrem.fr to creamhigh.fr , I need to reactivate the plugin “Product Variations Swatches”.
Can you revoke please the activation for aromextrem.fr ?

And please, tell me which licence key is available for creamhigh.fr.
I have another one (for extrem-lab.fr) and I don’t know which licence key to chose in my account, there’s no information about the domain.

Thank you in advance

Regards,
David
