What should I do about the server?

The two options that are:

Repair the ipad

I do not have the backup codes, and the authenticator with the codes are inside the previous ipad, the repairs of the ipad will cost around $150 to $200 approximately, which although it may work, there is a possibility that I lose the data, it is a 50/50 chance, plus get my old drawings back that are stuck on my old ipad.

Start from scratch ... again

But this time I would already have the authenticator in the cloud so with the possibility of putting it on several devices, in addition to having the backup codes saved on a hard drive.
