Is it possible to clone and/or move data from one Jira Space to another? (+ keep connections)

[Elyse Algate]

We are using connections and global fields across multiple projects. Currently, there is a limit of doing this with 20 Jira spaces. As a result, we'd like to condense down some of our Jira spaces. 

Questions:
- Based on research, it doesn't seem possible to clone an entire Jira Space. Is there a way to clone/move items in bulk from one space to another? If so, is it possible to keep existing linked data for items that are already connected and keep the multi-selections in place?
- If we need to use CSV files to export/re-import, is there a way to do this while keeping the existing connections in place (and relevant multi-selections and other field data)? Or would we need to import the data and re-connect everything in the new space (and re-do the multi-selections)?

Description Question:
- Is there a way to have your descriptions automatically show up in views? Is the only way to do this to have two versions - one that is included in the item and one that is a short-text field? 

Thank you for any help you can provide!
