Bambu Studio to PrusaSlicer

The two slicers agree about the model and about almost nothing else. PrusaSlicer keeps its settings as INI text under different names, in a different file, with the geometry in one part rather than one part per object.

How many plates fit?

Nine. A PrusaSlicer project holds up to nine beds, so a tenth plate and everything standing on it is dropped, and each dropped object is named in a Notes row.

Do modifiers and paint survive?

Yes, both. Modifiers, negative volumes, support enforcers and support blockers exist in both slicers under different spellings, so they cross unchanged, and PrusaSlicer keeps painted supports and seams in its model part.

What gets left behind?

Layer ranges and per-part settings. Those belong to Bambu Studio, OrcaSlicer and Creality Print files, and PrusaSlicer has nowhere to put them, so add them again after you open the result.

What are my settings called afterwards?

nozzle_temperature becomes temperature, sparse_infill_density becomes fill_density, and wall_loops becomes perimeters. Every name comes from PrusaSlicer's own field definitions.

Does the geometry move?

It is gathered into one model part, which is how PrusaSlicer writes a project. The triangles are the same ones; what changes is which file they sit in.
