I follow "https://docs.iredmail.org/backup.restore.html" steps to restore the LDAP database, but the data on the new server was not migrated properly,I see the Domains and Accounts and Admins information on the iRedAdmin page is correct, but I did not see the previous historical information in the system / Admin LOG
I have n’t seen any other letters on the Roundcube webmail page. It ’s an empty mailbox.
Excuse me, which link was not restored?
Please help to exclude, thank you very much
