Hi Ludovic,

Usually we backport only bugs fixes to keep LTS (11u) release stable.

To backport into 11u you need approval [1]. Here is example [2].

You need also point if backport applied cleanly or you have to make changes.

Changes should be backported separately to keep track - do not combine changes.
But it is okay to push both changesets together (especially if followup changes fixed first).
