when you try to copy a project from one database to anonther, you get a message Target Operator ID has 'No Access' to Upgrade. (62,14). This is despite you have correct permission list assigned to the userid in target database. This is due to bug in PeopleTools and is fixed in 8.46. Here is a workaround. Run this query in your target database.
SELECT * FROM PSAUTHITEM WHERE CLASSID IN
(SELECT OPRCLASS FROM PSOPRCLS WHERE OPRID='xxxxx') AND
MENUNAME='APPLICATION_DESIGNER' AND BARNAME='UPGRADE'
The operator class or permission list returned by very first row of query results, must have access to upgrade for that user. (AUTHORIZEDACTIONS = 4 for MENUNAME = APPLICATION_DESIGNER and BARNAME = UPGRADE).
Open Permission List, Go to PeopleTools Tab. Select Tools Permissions Link and Asign Full Access for Upgrade (at the bottom). Generally permission list PTPT1200 and Role PeopleTools has access to copy the project to target database.
