We have upgraded one of our test environment fom PT 8.49 to PT 8.50.10. After upgrade we found that our cutom permission lists which were added in My favorites ( Peopletools ->Portal->structure content->My favorites Folder security) are no more available. We are not sure what would have caused it to go away. We now see only 2 delivered permission lists. Has anyone experienced this? How can we retain those permission lists during upgrade or do we need to add them manually after upgrade? Please let us know.
