migrate ubuntu ext3 partition into ext4

hi

How is the best way to migrate ubuntu ext3 partition into ext4 without damage or lost data?

Were you looking for something like this. That ubuntu document seemed way too easy to find, that's why I wondered if you're looking for something else?

Thx, I've done according to:

http://www.debian-administration.org...xt4_filesystem

and it works well.
