Ok, now that you know your final goal I can try to answer :
first , A little background for other people who will read this and might wonder why this question exists (because it can help also in other cases )
the function get_page_by_title() does exactly what the name say . But qTarnslate , as well as other plugins , actually CHANGE the title in the DB .
The answer to such problems is using another less-known (but not less powerful) function called
why does this help ? Because the Path of the page will not be changed .
Usually it will be used like this :
But a much more cool thing is that the "path" parameter can be the SLUG , which is NOT changed by qTranslate .
so for the direct answer , please try this :
$page = get_page_by_path('your-slug-of-page-to-exclude');
that being said, and as a side note - there is no reason for you to lose the ID of pages when migration, if you simply export your DB and import to the new server , like described in the CODEX or HERE.
