SYMPTOMS
You are trying to migrate data using PMM but all databases failed to restore on the destination server with the error like:Failed deployment of database NAME (domain DOMAIN)
Execution of /usr/local/psa/admin/sbin/cid_unpacker /usr/local/psa/PMM/var/2007-01-11-16.39.23.122319 failed with return code 1.
Or you restored data from the dump that was made from Plesk CP or using 'pleskbackup' utilirty, but no databases' content restored.
CAUSE
Such problem may occur if there is the /root/.my.cnf file exists on the server and it contains the password that differs from the Plesk administrator password. In this case Plesk cannot connect to Mysql to dump/restore the databases' content because it passes the password to Mysql via environment variable, but the file has greater priority and Mysql uses invalid password from .my.cnf for the connection.RESOLUTION
Remove /root/.my.cnf file or use Plesk admin password in it.
