Thread:Project:Support desk/Migration of 1.12 on Linux to Windows 2008/reply

Hi!

I don't know of such a discussion, but if you ask me: What to do in which order depends:

I think that MediaWiki 1.12 will not be working properly with current PHP and MySQL versions. So if you move your old install to the new server, then it will be broken and you have to do a MediaWiki update in order to get it working again. Should you get errors afterwards (I am rather sure that you will), it is hard to tell, which of the steps you did (update PHP, update MySQL, update MediaWiki), caused it.

You have the old system and it works. So if the old PHP, MySQL and Apache versions still support MediaWiki 1.21, I would first update MediaWiki, get it running properly again and then move to the new server. That has the advantage that, should things stop working, you can more clearly say, where the problem must come from.

Apart from that take note that MediaWiki supports IIS and should work on a Windows server. However, although I use Windows myself, I would not run MediaWiki from there: It is just tested way better on default Linux installations, many problems you might run into have already been fixed on Linux and you have way more people running MediaWiki on Linux and so more support on Linux than on Windows.
