Buckworks has given you some top advice.
I beleive the key is in getting the right brains in place to act as insurance. Speak to either a good lawyer or accountant , but both professions must be involved. Consider a decent fee as the price of security of mind and pocket. Make sure you understand the technical implications as well in the transfer - a " change document " is vital.
You have to consider warranty , idemnity , intellectual property , funds , title , recourse if things break down , jurisdiction of law , taxation , securing the contract etc etc . For a small amount no such consideration is needed - but this is a good amount and $10 to $20k would be good security. Make sure the skills are from a specialised commercial lawyer / accountant. A middle tier firm is what you should consider as their fees will not be as high.
Good luck and congrats on achieving this level.
