How can I export a scoped application to another instance, unrelated to my current company and continue to develop there?

[Kristian Johns3]

I am an SA for a company that is going through a merger. I've developed a scope application in the development instance of my company (Company A). We are reimplementing our ServiceNow implementation on a fresh instance that belongs to Company B. I need to port my scoped application from Company A dev instance to the Company B new dev instance. Exporting the application to an update set didn't work, as the sys_app table wasn't updated on the new dev isntance. Is there any way to port the application from the instance of one company to the other so that active development can continue on the new company's instance?

Downloading the full update set of the latest version of the app and uploading it into the other instance allowed me to continue development on the new instance as intended.
