I have recently completed migration of our on Premise Confluence instance to the Atlassian cloud. I did this on a Space by Space basis with export and import (there were reasons for this).
What we now want to do is to set up some sort of redirect from the old instance to the new one so that people are not forced to fix their links/bookmarks.
This isn't quite as simple as that though, because the URLs of the new site are different to the old site. An example: /display/WBP/Beckelmann becomes /wiki/spaces/WBP/overview.
We have used the REST API to build a mapping of the pages, but I am struggling to work out the best way to implement that. Has anyone had any experience with this, or got a guide I could read?
