If you started the license transfer on the console you already used anyway, then it won't do anything since you already had the licenses on that console.
The license transfer will transfer licenses for all of your DLC. There is no way to specify which ones to transfer.
Did this solve your problem?
Sorry this didn't help.

Sorry to say this, but you can't re-transfer licenses for another year/ twelve months.

The time between transfers has been dropped to once every four months.
Thanks for the quick replies. Will this have any affect on moving my data onto a bigger hard drive while using the same Xbox?
It should not affect moving to a larger hard drive.
It pays attention to your console ID number - which is like its serial in regards to live. Harddrive/storage changes won't cause any issues.
