If you use Backports

In general, backports.org only has backports made from testing but with reduced version numbers (apt considers ~ lower than -), therefore the upgrade path from etch-backports to lenny is saved. However, there are a few backports only which are made from unstable (security updates and the following exceptions: firefox, kernel, openoffice.org, xorg).

If you do not use one of these exceptions, you can safely upgrade to lenny. If you use one of these exceptions, set the pin-priority (see man apt_preferences) temporarily to 1001 for all packages from etch, and you should be able to do a safe dist-upgrade too.

This behaviour has been confirmed by the backports team in this [http://lists.backports.org/lurker-bpo/message/20080930.090902.0f29d785.en.html mail].
