Hello guys,

I've read some articles in this forum about migrating ZCS to ZCS, but still have some doubts about it.
Following the article ZCS-to-ZCS Migrations » Zimbra :: Blog and running the command:
/opt/zimbra/bin/zmmailbox -z -m user@domain.com getRestURL “//?fmt=tgz” > /tmp/account.tgz
I've found the error:
ERROR: zclient.IO_ERROR (invoke java.security.cert.CertificateException: Untrusted Server Certificate Chain, server: localhost) (cause: javax.net.ssl.SSLHandshakeException java.security.cert.CertificateException: Untrusted Server Certificate Chain)
I've read this article: Recreating a Self-Signed SSL Certificate in ZCS 4.5 & 5.0 - Zimbra :: Wiki
and I think that it will help me to fix the error. But the article about migrating refers to Zimbra version 5.0.9 and mine is 4.5.10. So, my question is: is there any problem with this command when it is applicated to 4.5 version?

Best regards,

HTR.
