New phone using same Icloud, that old phone received permanent snapchat ban ( please see questions below )

Hey, I received a permanent Snapchat ban 2 years ago on my current iPhone 11. I've read through numerous forums on here but just wanted to double-check to be on the safe side.

I am upgrading to a new phone.

1. Can I use the same iCloud or not? If yes, can I still use backups to restore data to the new phone or not?
2. The number on the phone with the ban was never used within the snap account. I presume this number would be ok to use on the new phone?

Thanks in advance.
