DMSI 3.1A to 3.1B or 3.2B?

[Benjamin]

Am I switching products though? DMSI A to B, a break is required between them? Isn’t B the same as A without the healing stuff?

If it was the same version it's fine. But each version is significantly different so the P6 21 day rule stands. After 3.2 it's even longer, like 35 days or something, that's on the sales page.
