Hi All, I tried to transfer a cpanel account to a new server by transfer tool but I received a following warning: The server failed to synchronize "test@test.com""s mail because an error happened: (XID bd3hhg) "/usr/bin/dsync" reported error code "75" when it ended: Cpanel::Exception/(XID 75ajcy) Access Denied at /usr/local/cpanel/Cpanel/CpXferClient.pm line 273.

May I ask if this warning can be ignored or not? Thank you very much! Tom

If all the mails are there then it can be ignored. The error says that dovecot (IMAP server) returned an error while synchronising the mails: Error: read(remote) failed: EOF (version not received) doveadm(31740): Error: Remote command returned Are you transferring from an EOL server like CentOS 6 to a newer server?

Yea, both old and new server are running CentOS v7.9.2009. By the way, may I know if I can "Pretransfer" the account to the new server so I can use the option "overwrite" to only update the modified files in order to speed up the migration process? Thank you very much! Tom

Overwrite will transfer everything again so unfortunately you can't pre-transfer easily from WHM but manually using rsync.

The transfer tool needs one hour to transfer the whole account but only needs 5mins to complete the overwrite process. It seems that "overwrite" uses rsync?

I was wrong, I apologise. You are absolutely correct. It does rsync the data what has changed and won't transfer everything over again. There was an old thread about this as well:

@cPanelAnthony can you advise here why the "overwrite" option during the transfer might not sync the emails correctly?

May I ask if I can remove all emails by deleting all folders and files in /home/user/mail via ssh?

You can easily remove all email accounts from cPanel, that would be safer.
