Importing another account on my premium account

Hi

I had two Clicky accounts for two separate websites for several years now. I upgraded one of these accounts to premium and I can add several websites to it. Is it possible to import data from other websites in the other account to this premium account? I know I can manually add it but this means I will lose the analytics data that has been there for years on the other account. Please help. Thanks.

Not possible via the interface. Might want to contact Clicky directly.
