Live to test content updating

Hi All,

First time posting and using Contentful, so apologise if this is the wrong forum!

I’ve never used Contentful previously, and now have been tasked with overseeing a Contentful site. Our Staging environment is quite out of step with our Main environment content wise, it would be really useful if I could bring Staging up to date in line with the Main.

Is there something I’m missing? How would I go about copying the Main content over to Staging?

Thanks
Soph
