My company purchased another company, elements in the parent company want to bring the purchased companies Confluence server instance data into our Confluence cloud instance.
I can find articles about cloud to cloud or even migrating from server to cloud but this wipes out all data on the confluence and replaces it with the imported data, I don't need that, I need to maintain our data in our confluence cloud, and basically bring in the data from their confluence server.... happily living together all in the same instance without any trouble (lol)
I did find this but its talking about merging 2 server instances https://community.atlassian.com/t5/Confluence-questions/Merging-two-confluence-instances/qaq-p/180999
But it sounds like it might work for what I need, I just dont know what my limitations would be, In any event im looking for some guidance on this from people who know and understand this alot better than myself 
Thanks,
- Mike
