Hi Experts,

Can anyone tell me if there is a possibility to migrate MediaWiki 1.16 on Windows Server 2003 (32 bit) to Windows Server 2012 (64 bit) ?

If the above is not possible will we be able to upgrade to 1.22.2 on Windows Server 2012?

Thanks, John Dennis

1.16 is no longer supported, and we strongly encourage people to upgrade to 1.22.2 as 1.16 no longer gets security fixes.

There should be no issue with migrating to a 64bit server. If the server has a different domain or url scheme, you might have to change a couple variables in LocalSettings.php if they reference the domain of the server. Otherwise there shouldn't be any problems. If you are using UCA category collations ($wgCategoryCollation), changing versions of PHP can cause problems, however that feature is off by default.

> if they reference the domain of the server

That is usually the case for variables like $wgServer.

I just completed an upgrade from 1.16 to 1.23wmf11. Granted I'm on linux, but the upgrade was relatively painless. You can contact me if you have questions about how we did it.

You should have followed Upgrade and that's it. It's all in there. ;-)
