Certification Authority – CA Signature Algorithm: sha256WithRSAEncryption or ecdsa-with-SHA256

I need to update a CA that is about to expire, is currently using Algorithm of signature 256WithRSAEncryption and I'm thinking of using ecdsa-con-SHA256 with something like:

openssl req -x509 -nodes -days 3650 
-newkey ec: <(openssl ecparam -name prime256v1) 
-closed certs / CA.pem -out certs / CA.crt -subj "/ CN = myCA"

In addition to updating, recreating existing certificates, I wonder if there is anything that I should take care of when using ecdsda firms
