Manual:Merging histories

Merging page histories is done using Special:MergeHistory. This lets the user merge revisions of the history of one source page into a newer page. The user can use the radio button column to merge in only the revisions created at and before the specified time. Special:Log/merge will then present the user with an "Unmerge" button to reverse the merge. This is done by switching the source and destination pages in Special:MergeHistory.

Merging pages works by changing the rev_page field in the revision table. When merging, the selected revisions from the source page will be set as revisions of the destination page.

logging.log_params holds the page title of the destination page and the timestamp.
