We show how to systematically construct integrable deformations of current algebra based CFTs and the effective all loop $\sigma$-model actions. We evaluate exactly the beta-function and anomalous dimensions of operators. Our techniques use leading order perturbative results, non-trivial symmetries in the parametric space of these theories as well CFT and gravitational methods. We explicitly provide flows between exact CFTs in the UV and IR regimes which is rare occasion in the literature. Embedding to type-II supergravity is demonstrated.
