This topic comes up a lot.In the UK at least it is virtually impossible to move from TI (or EA) to Strategy within Deloitte. At grad level, Strat gets approx 2x the applications of the other four service lines combined (HC, Ops, TI, EA). And it is the smallest service line. The strat vacancies always go first, and many strat applicants end up in HC, EA and TI because Strat is believed to get a higher quality of applicant.So there are many people in your position. If HR was to allow one person to move across it would set a precedent which would see them engulfed with similar requests. It is just not done. Especially as you are trained in your sector/service line specific area straight away. You may have a slight chance of getting into some strat houses with TI experience, but only into areas where you can use your experience.What many people dont realise is that TI is the real growth engine with the green dot. It is the best performing area and positions are still very competitive. There is no shame in working within TI.
