How can I see the workflow history prior to migration for each page in my cloud site?
Currently, the page activity† for each page is not migrated to Cloud.
Solution
If the workflow history is required, one option is to download the page activity as a CSV file for each page. This is a manual task and although it can be a scripted operation, the scripting may not be simple.
If your organizational requirements include a Compliance/Regulatory audit, you may need to keep your legacy Confluence server instance (in read-only mode) so auditors can review the historic workflow history/page activity for your content.
†In cloud, page activity is accessed using the Workflow History option in the page tools menu.
