Notice:DBManager.php on line 835 after upgrade from sugarcrm CE

after successful upgrade from sugarcrm CE6.5.20 to suitecrm, I got below message
Notice: Array to string conversion in C:\wamp\www\crm\include\database\DBManager.php on line 835

Database failure. Please refer to sugarcrm.log for details.

is my upgrade ok? should I ignore this message?

you upgraded to which version? is that the exact line that you got from sugarcrm.log?

best regards
