Thread:Project:Support desk/Importing a old installation from database backup/reply

Hi!

Old versions of MediaWiki can be downloaded; see here: http://dumps.wikimedia.org/mediawiki/

Yes, upgrading a database from MediaWiki 1.4 to newer versions is possible. To do an upgrade, check the information on Upgrading. Especially this section may be important for you.

PS: Note that to restore your complete installation you might also want to restore "personal" files like images, which were uploaded to your installation.
