It sounds like the sequence of commands you're looking for is

/END DATA/,$d
q
.a
NEW END
.
wq

or as a one-liner

printf '%s\n' '/END DATA/,$d' 'q' '.a' 'NEW END' '.' 'wq'

(You can replace wq with ,p for testing.)

Ex. given

$ cat file
Data 1
Data 2
something_unimportant_here END DATA
Rubbish 1
Rubbish 2

then

$ printf '%s\n' '/END DATA/,$d' 'q' '.a' 'NEW END' '.' 'wq' | ed -s file

gives

$ cat file
Data 1
Data 2
NEW END
