Pop quiz: I have a Dutch installation of SharePoint (WSS 3.0 or MOSS 2007) that already contains a lot of data. I want to restore the main site collection on a different server with English installation of SharePoint. Can it be done ?
Take into account that a localized version of SharePoint requires specific resource files on disc based on LCID (en-US = 1033, etc).
Yes, you can ! But you will need the correct Language Pack for it to work. Otherwise it will just throw a "500 INTERNAL SERVER ERROR" at you.
