can I copy nginx cache from server to server?

Hi All,

I have an nginx server with 100GB cache files of images,
can I copy the cache folder to another nginx server?

am i missing some index map for the cache , or will the new nginx server be able to use its new local cache as is?

the configuration of the new servers is identical to the first including file paths and all.

thanks in advance for your thoughts,
Yonit
