Help:Importing and exporting pages

Sometimes you need to export pages from one Fandom community to another. Or you may want to grab some pages from a non-Fandom wiki, like Wikipedia. You can do this by using the Special:Export page on the donor wiki — and the Special:Import page on your wiki.

Anyone can use Special:Export. It simply creates an XML file of the pages you choose. But you have to be an admin to use Special:Import, the page which unpacks an XML file into pages on your wiki.

Before exporting
Special:Export is commonly the cleanest way of adding a series of one MediaWiki site's articles to another MediaWiki site. This is because when imported, licensing data and attribution transfers over, keeping the content CC-BY-SA compliant.

That said, it is not always appropriate to export content from a site. The content should be exported so that the importing community can use the content in a new and unique way or in a different context. For example, you might import Marvel's page about Thor into a community about the movie Thor. Or you might import a series of pages from an English community into an international community so that they can be translated more easily.

As a rule of thumb, keep in mind that others have created the pages you are exporting. Simply importing their work for no other reason than to have their work is something you would likely not appreciate if they did the same to you. Consider whether it might be more appropriate to link to the page on their wiki instead of copying it.

Exporting

 * How to deal with a "collision"
 * When importing content you may come across pages at two different communities that have the same name. In this case, one of the pages is going to have to be renamed before doing the import. You can't do it afterwards. If you forget to do this, the edit histories of both articles will get fused, and you'll typically end up with a page history that's simply too confusing to be understood.


 * Generate a list of articles
 * The simplest way to get a list of articles is to use the "Add pages from category:" field at the top of the Special:Export page, which will automatically add a list of articles in a given category to the Export list.


 * If that isn't possible, you can copy and paste lists of article titles from a Category page, Special:AllPages, a DPL list, or any other source of page titles. You might need to work with the pasted list in your favorite external notepad, word processing, or spreadsheet program to get a list of plain page titles with one title per line.


 * You must include the namespace if you wish to export from anything other than the main article space (e.g., Talk:Something, User:Someone, Template:Infobox).


 * If the list is long, or the pages have many revisions, you will probably need to break the list down into smaller chunks, as MediaWiki cannot import XML files larger than about 1.8MB.


 * Choose whether or not to include page histories.
 * Including page histories is almost always the best choice, as it makes the required Creative Commons attribution for authorship much simpler. Unless you have a specific reason to want only the latest version, uncheck "Include only the current revision, not the full history".
 * You may need to leave "only current revision" checked for articles that have very long histories. If you do, please mention the source in the Special:Import comment field so that anyone investigating the page history of an imported article can see where it came from.


 * Choose whether or not to include templates.
 * Checking this will export all templates and sub-templates required by the page. If you do not export them, the pages may not display properly when imported. You will either need to add the templates to the destination site later, or edit pages to remove template code.
 * Some wikis, including Wikipedia, tend to use lots of intricate and flexible templates and sub-templates, developed over many years by people who specialize in their construction. They're often a lot more complicated than you need at Fandom. Be prepared to either import a lot of templates and sub-templates to make imported Wikipedia pages display properly, or to edit the pages after import to remove or simplify the template code.


 * Save the exported file.
 * Check "Save as file" to save the export to your computer as an XML file. If the reported file size is larger than about 1.8 MB, you will need to reduce the size of your Export list and try again, so that you can import the desired pages in smaller chunks.

Importing

 * Import the file to the new community.
 * Import UCP.png
 * Go to Special:Import on the destination community and click the "browse" button to find the XML file on your computer. The imported pages will be listed on Special:RecentChanges and on Special:Log/import. You can only do this if you are an admin on the wiki you are importing to.


 * Provide credit, as required by our license
 * Wikipedia is a common source for wikis to use content from. If you copy Template:Wikipedia to your wiki then you can add to the bottom of your imported page to provide the required attribution for anything copied from Wikipedia.


 * You can also create copies of this template to use for other sources. For example, if your specialized cooking community borrows a set of recipe and ingredient pages from Recipes Wiki, then you could create a similar "Template:Recipes Wiki" to provide links back to that community.


 * Make changes for your community
 * Once imported, you might like to move/rename the articles, and edit them as you would any normal page. Most importantly, you want the pages to fit with everything else on your community.


 * You should change the tone and vocabulary used in the text if it's out of place, add links to existing pages on your wiki, and add appropriate categories. You might also split long pages into multiple shorter ones, remove or simplify template code, and either remove unwanted red links (links to non-existent pages), or change them to interwiki links that point back to the source community.


 * Interwiki prefix
 * This is the prefix that will be used to link the changes to the appropriate wikis. For any Fandom wiki, you can simply use, replacing wikiname with the name of the wiki given in its URL (for example, for community.fandom.com, this would be community). A full list of other prefixes can be found at MediaWiki:Interwiki map.


 * Assigning edits to local users
 * If this option is checked, then the username displayed in the pages' histories will link to their profile on the local wiki, and if it's unchecked then it will link to their profile on the wiki defined by the interwiki prefix above. If you imported the pages from a non-Fandom wiki, this should definitely be left unchecked. If this is from a Fandom or Gamepedia wiki, it's still better to leave it unchecked unless you know everyone in the page history is working on your current wiki.


 * Additional import options
 * There are 3 options beneath the comment for where to import the pages to:
 * Import to default locations
 * This is the default option which will import the pages and categories in the XML file to the same page names in the destination wiki. This is the correct option for almost every use case.
 * Import to a namespace: [select the target namespace]
 * This option allows you to import all the pages in the XML file to a namespace other than the main namespace. Be careful using this option as it can have unintended consequences.
 * Import as subpages of the following page: [specify the page name]
 * This option allows you to import all the pages in the XML file as subpages of a single page. This will not work for categories.
