upgrade XP prof X64 English to Win7 Ultimate X64 Dutch

Ok, i'm dazzled by the many websites with each a different opinion, upgrade paths, and so. It took me hours of reading and clicking. I'm nearly fed up. So finally made it to this forum. With my question:

Is it possible to legally upgrade from XP professional X64 English (OEM) to Windows 7 Ultimate X64 Dutch? Retail or OEM needed?
BTW: Win7 Professional X64 Dutch would be a good alternative.

It's unclear to me if it' s allowed to switch from an English OS to a dutch OS. Some say any new OS MUST be the same language as the old one. But is this also appliable for the Ultimate version, since it can switch to other languages after install?
I will be doing a clean install.
Further on i am struggling with the ' professional' to ' ultimate' switch. In some cases that path would not be allowed, others say it is allowed.


Thank you in advance for an answer to my questions.
James.

PS
Very confusing MS-marketing!
What we'd need is a wizard containing all the different choices and possiblilities. Simply choose the old OS from a drop down menu and the new OS, and it would tell you YES thats possible or NO, impossible. And under what conditions. Would draw a lot of site visitors.
Just my 2 cents.

Hello Snowy, welcome to the Seven Forums.

An in-place upgrade is language dependable, the language of old OS and new OS have to match. You can not do an in-place upgrade, keeping your installed software, from XP to Seven. Seven is in-place upgradeable only from Vista.

So the answer to your question is YES, you can upgrade from English XP Pro to any version of Dutch Win7. You have only one option, to do a clean, custom install and this can be made with Upgrade version of Seven in any other language. Using an upgrade version to do a custom install in other language than the old Windows is always possible.

A bit confusing, I hope you can understand.

Kari, thanks!

In addition to your answer another q: does it make any legal difference my old OS is OEM (i bought it second hand on ebay), instead of retail?

No. As long as you have an existing older Windows, you are entitled to use the upgrade version of Seven.
