chadwickgendron on "Transfer of upgrades"

No, my question is that CCT and EUL had upgrades such as domain name (without .wordpress) as well as additional space. These 2 sites have been moved. I thought I could transfer these upgrades that I paid for and have time remaining on, to other sites that I currently possess through WordPress.com such as princesskateandprinceholden.com and a new one tenpointreview (as well as a couple of upcoming new ones) that was set up but does not have any upgrades yet.
If this is not possible then what is the transfer? It seems that what I want to do is what this feature implies.
