We had the same challenge last June when we flew to Mauritius via Paris from Malaga. We had even less than an hour in the end because the plane from Malaga was delayed by 10 minutes, so we had 50 minutes to change terminal at Paris CDG.

We contacted the airline company beforehand to explain the situation and ask for assistance on arrival in Paris due to the short change over time. We got all our boarding passes when we checked in in Malaga for our flight to Paris and on arrival in Paris there was someone waiting at the gate to take us to the other terminal. It worked absolutely fine like this.

Did you use a travel agent to book your flights, or did you do it via the internet?
