Overried translation i made?

[Goodman_2020]

Hi,

Upgrading from 3.6.9 to 3.7.2 was a real mistake, especially because of lot of templates which were not updated to 3.7.2.
I installed french language, and translatedduring hours and hours phrases already translated, to make them what i wanted to be.
So i decided to recreate all my forum with a fresh 3.7.2 instalaltion.

Is there a way to override all my expressions and phrases from 3.7.2, with those i spent hours to re-translated to fit my needs? If yes, how please

Thx
