Assuming same company, agree; but SDRs are kinda pinned at one company until AE promo and then enough sales cycles to get hired elsewhere, else a switch resets their promo clock - SDR to rolling the dice on an AE role that may or may not pay more to AE at another company with an actually good AE role is a common pattern. Esp since companies usually underpay recent SDR promos since they are so happy for the swap, so switching companies once AE skills fungible often worth $xxK
