Troubleshoot through Uploads folder

Hi,

I have 2 websites. Old and New.

Old is on address https://www.site1.com and all it’s content is in subfolder /sub

Now, I am building new website that is on https://www.site2.com and it’s content is in subfolder /newsub

I want (after I finish new website) just to redirect content from subfolder /newsub to https://www.site1.com. What I wish to know is will my uploads from subfolder /sub be showing on new website because now it’s https://www.site1.com/content/uploads
