Single-word replacement for "To be replaced"
I'm looking for a word to describe an old item that is soon to be replaced.
Temporary was the first thing that came to mind, but it didn't seem to fit in context as the old object has been there for a long time already so is hardly an interim substitute.
Solution 1:
You might consider obsolescent or obsolete.
obsolescent adjective [ODO]
becoming obsolete:
obsolescent equipmentobsolete adjective [ODO]
no longer produced or used; out of date:
the disposal of old and obsolete machinery
If it's simply to be replaced due to wear-and-tear, and its replacement is essentially the same, then worn out or the more jargon-ish "end of life" might be better.
