How to Do an Advanced Merge on wikiHow (Merge Page History)

When merging two wikiHow pages, the recommended approach is to do a standard merge where you move content from one page to the other and create a redirect between them. Occasionally, however, you need to merge a well-established page, in which case you'd want to preserve the page history of both articles. This is done rarely but if needed, the instructions are provided below. Full administrator status is necessary to perform all of these commands.

Steps

    Use the advanced technique only if:
    • the article you're merging was featured at one point (check the discussion page)
    • it is a very popular and thorough article (over 50,000 page views and in-depth instructions)
    • the article was donated by a third party (e.g. VideoJug, Wired Magazine, Family Handyman, etc.)
    • the article has a very long edit history (over a year old, more than 10 contributors, etc.)

    Identify the two pages to be merged. For simplicity let's call them "Merge Target" and "Merge Source". "Merge Target" will become the final name of the page.

    Determine which page will become the Merge Target by selecting the page with the shorter, simpler name that more people will search for. When in doubt choose the article which has more page views since that one may be linked more frequently on other websites.

    Move all of the good ideas from Merge Source into Merge Target (what you want the name to be). Edit Merge Target just as you would a regular article.

    Find all of the articles that link to the Merge Source.(Toolbox: "What Links Here"). Change the link on those articles to point to the Merge Target.

    Move "Merge Source" to the "Merge Target" (the one you just deleted) name. (Toolbox: "Move this Page")(Make sure you type the Target name exactly. Easiest way to do this is to use your cursor to copy and paste the article title, omitting the words "how to".)

    Confirm that the page and page history of the new page now contain the authors of all previous versions of both pages and the content shows as you wanted it. Make sure the article is a good candidate for merging. Take a look at the merge policy and compare the titles (ignore the content for now). Do the titles mean the same exact thing? If they don't, merging isn't a good idea here. Remove the merge tag and place a note on the discussion page explaining how the titles are different.

    Read the Title Policy for information on determining whether two titles mean the same thing.
