how to map page ID from version history content ID

[JQ]

hi 

I'd like to seek help with a data question

I followed https://confluence.atlassian.com/confkb/how-can-i-export-page-version-history-details-for-a-given-space-965567214.html to get all page version history, though the content ID is one of the columns, it appears to be the version's content ID rather than the page ID

page ID can be used in other cases, e.g., to map further with other reports, especially if page title changes over time, to tell abt "the life of page(s) - when it is created, how many edits done to it month to month, how many views it has month to month..."

does anyone know how to map it?

thank you in advance!
