Replacing fixtures globally on Ion

Hey fellow tech heads. Quick question, I've taken over a show file that runs channelling starting from a zero, such as 100, 101, 103, instead of 101, 102, 103, 104. I want to change it so numbering starts from 1. Is there a way to replace a fixture globally on the ion? I know I can use blind and "copy to" or "recall from" to copy the values in cue lists and subs etc, but is there a way to replace a fixture entirely, so that macros, palettes, presets, groups, cues and all other plotting change with the replace command? Sorry for the length! Help a brother out Cheers
