We don’t have any capability in place for scheme switching just yet. It should be coming out end of July

> Hi @swanhong CoefPackedPlaintext is currently supported only for BGV and BFV (for the case where numbers modulo t are encoded). We have not seen yet a need for a coefficient encoding in CKKS (as a user feature). All use cases we have seen typically work with the CKKSPackedEncoding encoding. The coefficient encoding internally comes up in CKKS bootstrapping or scheme switching from CKKS ↔ FHEW, but these are handled automatically by the library using methods like SlotsToCoef (still operating on …
