For what it's worth, I've just had a look at Merriam-Webster.
Rebrand: change or update the brand or branding of (a product, service etc.)
or: (broadly) refer to or describe in a new way
[examples given suggest to me that rebranding is done by the owner of the brand]
repackage: to package again or anew
or (specifically): to put into a more efficient or attractive form
[I also looked at a dictionary of real as opposed to north American English but need not trouble you with the definitions there, for fear of arousing European speculation]
