How to share content betweein two instances of confluence?

[Matej Kamenicky]

We have two instances of confluence, one in the secure environment and one accessible from the outside of the company.

We would like to share content of certain Spaces from the one instance to the second one.

Is there any possible solution how to connect our two instances and share the content without buying add-ons?

Hello @Matej Kamenicky 

Currently, I don't see any effective(even paid) solution available for this requirement. You can connect 2 confluence instances via application links but that's it. You can't do much. 

Especially if you want to publish some content from secure instance onto the public instance then there might be hackish sort of ways available for achieveing it but out of the box it's not supported nor do I know of any effective plugins. 

There is this plugin, which you can look into but it's paid -https://marketplace.atlassian.com/apps/1212746/scroll-remote-publishing-endpoint?hosting=server&tab=
