Are 32 and 64 bit keys interchangeable on 2008 Server Standard

We're going to be migrating a server running 32 bit Windows 2008 Standard, and we would like to migrate it to 64 bit. Is this possible using the same key?

The product key should not be architecture specific. The only problem I can imagine you'd have is if you are not doing an in-place migration, one of your servers won't be activated.
