Issues changing an ubuntu package from native to non-native?

[Andreas Hasenack]

Hi,

I would like to change a source package in ubuntu from native to
non-native. The main reason is that I personally have a hard time
dealing with native package, specially one that spawns multiple ubuntu
releases.

While I could perhaps be convinced to keep it as is, or learn how to
properly deal with such packages, I think the question is still valid:
is there a precedence or best practice to follow when converting a
native package to non-native? And can that be done together with an
SRU as well (the SRU itself being driven for other reasons, and this
change would just piggy-pack on it)?
