Which of one I should not do? 

I fear, that when deleting any entries of the previous release, it might want 
to deinstall packages ("applications" in this sense) from bookworm I want to 
keep. My thoughts are, if these will be kept, then on one hand it might block 
install of packages from trixie, but on the other hand it wil not break the 
system. 

But, on the third hand, this thinking might be complete false.
