OJS3 French canadian translation

Hi,
I read in another post ([OJS] Language translation not working in 'Workflow Settings' and 'Submission' · Issue #1505 · pkp/pkp-lib · GitHub) that some files need to be translated before doing any journal creation or before going live on production. These are:
-/ojs-3/lib/pkp/locale//default.xml
-/ojs-3/locale/
/default.xml

Are there any other ? If not and if these files are correctly translated, can we assume that we could go live (production) and make some slight corrections to other translations files after, without “breaking” anything in the database ?

Regards,
Pierre
