Life is a journey; that may also mean you held a series of jobs in that antiquated field with no real immediately-obvious benefit to discussing them in your LinkedIn profile (unless a recommendation from a former colleague in that period is so outstanding).
The dilemma is to show your entire years of experience without boring the reader. You don’t want to leave out any period of time as that makes the reader’s mind wander, and that’s not what you want.
