### Lifting polynomials

Hello!

I have this polynomial 'fp' that I'd lite to lift to ZZ. How do I go about doing something like this in Sage online?

```
Univariate Quotient Polynomial Ring in y over Ring of integers modulo 127 with modulus Y^23 + 126
fp=y^21 + 126*y^19 + y^17 + 126*y^16 + y^15 + y^14 + y^13 + y^12 + y^9 + 126*y^8 + 126*y^5 + 126*y^4 + 126*y^2 + 126*y + 1
Univariate Polynomial Ring in X over Integer Ring
Q.<X> = PolynomialRing(ZZ)
```

Best regards!
