I haven't seen details on whether the database has stayed the same, or what the details of any schema changes may be. If there's a file that calls them out, please let use know.
If not, the INSTALL, UPGRADE, and RELEASE-NOTES files of the mediawiki release provide information for upgrading, and they start with "It is imperative that, prior to attempting an upgrade of the database schema, you take a complete backup of your wiki database and files and verify it." That's a pretty good commercial for not doing what you'd like to do and either moving to another machine (or a virtual machine). For what it's worth, I needed to change the home directory of one of my sites. I did what you're asking about, but it was with the same version. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Henny Savenije Sent: Monday, September 20, 2010 4:16 AM To: Uwe Brauer; MediaWiki announcements and site admin list Subject: Re: [Mediawiki-l] connect to wikis to the same database?
