Admin Forum:Merging a wiki

Can someone explain what it exactly does? — ¤ U LTIMATE S UPREME ¤ (T@lk) 11:08, June 18, 2012 (UTC)
 * There are two methods to merge two wikis: simple copy–paste and importing. The second one is preferred because it preserves page history and contributions; one needs to go to Special:Export on the wiki to be closed, give it a list of pages (from categories or manually), save the XML file it outputs to his/her computer, go to Special:Import on the other wiki and upload the file(s). Exporting requires no user rights, while importing requires the user to be an admin. 11:36, June 18, 2012 (UTC)
 * Ok. Can I import images? — ¤ U LTIMATE S UPREME ¤ (T@lk) 10:38, June 25, 2012 (UTC)
