[Решено] Different Language URL format in Staging and Production site.

Hello,

I would like to know if I can use 2 different settings for the language URL format.

Use formatting with directories or with the "lang=" parameter while the site is being developed and translated.

Then, a different domain for each language when the site goes online.

I'm asking because the site is accessible via a test sub-domain during development, then it will be accessible via the main domain.

Are there any precautions to be taken?

Thank you
