ssl certificate renewal - keytool error: java.lang.Exception: Certificate not imported

Hi,
I just renew our GoDaddy SSL certificate and I am trying to import it into keystore.jks and cacerts.jks using:
keytool -import -alias v2apps.eurobit.com -keystore keystore.jks -file v2apps.eurobit.com.crt
keytool -import -alias v2apps.eurobit.com -keystore cacerts.jks -file v2apps.eurobit.com.crt
All is fine for keystore.jks but with cacerts.jks I am receiving this error:
keytool error: java.lang.Exception: Certificate not imported, alias already exists
Any idea?
Regards,
Gabriel
