export-import spaces for server

[aviv_cohen]

HI,

My environment (staging & production)based on 2 server nodes. Same version (6.15.8)
I'm trying basically copy space from production to staging for testing

I've used the following tutorial to perform it:

https://confluence.atlassian.com/conf615/export-content-to-word-pdf-html-and-xml-967337418.html

https://support.atlassian.com/confluence-cloud/docs/import-a-confluence-cloud-space/

The outcome is that on the staging server, I see only partial data of the full space in production

Reading here I understand that this is not the best practice to do, but again I'm using Confluence server so I can't use the cloud utilities

Pls. assist
