If you're not in the US, let me first point out that Azlo doesn't even support international transfers. They do not have login system for multiple founders. I'm very sure they don't work with ITIN and require SSN to open an account. Also, only one debit card. No checkbooks.
It appears that you somehow expect every step of the process to be smooth as butter. But nothing about running a startup will be like that. Transferring subscriptions from one Stripe account to another should be the least of your problems when porting an existing business with transactions to a c-corp. Talk to a lawyer and an accountant to understand what you got yourself into. Since you're trying to migrate transactions before the incorporation into the company account, you should talk to them earliest you can.
