SM9.4x Hybrid then back to Codeless and Codeless to Hybrid

If we choose to go from SM9.21 to 9.4x Hybrid, might we ever need to switch to Codeless?  If so, could we and how is that done?

Conversely, if we go from SM9.21 to Codeless, might we need to switch to Hybrid?  If so, could we and how is that done?
