cPanel full backup restoration failing at database stage?

hey all, i'm hitting a wall trying to perform a full backup restoration for a client's cPanel account on a new server. the process consistently bails out when it hits the MySQL database import, even though i've double-checked file permissions and the database user seems configured correctly. the specific error log entry is pretty repetitive, looks like this:

ERROR 1044 (42000): Access denied for user 'cpaneluser'@'localhost' to database 'cp_database'

this is despite granting all privileges to that user for the specific database. wondering if anyone's faced this exact database-stage failure during a cPanel full backup restoration. anyone faced this before?
