Can I simply migrate content from Bitwarden to Vaultwarden?

I couldn’t tell from looking at the faq or wiki.

Does anyone have a handy guide to switching to selfhosted version? I was considering doing that but I let my plan renew out of laziness.

The SDS will be for the oil itself, not at the final concentration used in the shampoo or whatever.

Are you sure the final product is at a toxic concentration? Probably the detergent itself is more dangerous as used. That’s just a guess though.
