If yes, I can create a new ad account in the same Facebook account? Or to create a new Facebook account?
If you don't have access to your old store. Then you should create a Business Manager account, which is where you can make a second Facebook Ad Account. You can also add your old ad account to this new Business Manager account. With a new ad account, you will get a new pixel that you can add to your new store. Follow the link about for how to create a business manager account. Hope you found this helpful, if so please click "like" below to let me know.
