I need to compare the calculated ckks ciphertext. May I ask whether openFHE has a conversion method for CKKS and FHEW ciphertext？

I assume you mean you want to compare encrypted values.  
CKKS\<-\>FHEW scheme switching is currently in testing, we plan to release it in the next major release.  
@ypolyakov may have more details on this.

@hamm As @dcousins mentioned, we are going to add CKKS\<-\>FHEW scheme switching in v1.1. We have a prototype implementation, but it is not ready for public release yet.
