to shift, to transfer, to translate
迻 centers on moving something from one place or form to another: shifting, transferring, or translating.
迻 combines 辶 (movement) with 多, which likely contributes the sound and suggests multiplicity or change, together expressing the idea of moving or shifting.
The movement radical 辶 wraps around 多 (many). Picture many things being moved along a path: shifting, transferring, or translating them.
For イ, imagine an eagle (イーグル) carrying many things along a path, shifting them from one place to another: eagle -> イ.
