Support Bulletin: User permissions not correctly migrated
Automated migration of user permissions from version 2.6.5 (acls.xml) to version 3.0.0 (permissions.xml) can result in some users having more privileges than they had before the migration.
After the migration, an administrator should log in to the Administration perspective, go to the User Management : Permissions topic for the repository scope, and review and adjust user permissions. This should also be done for any projects which override the default configuration.
The main problematic part is if you changed something in the “GLOBAL SECURITY SETTINGS” section of acls.xml - due to the different logic behind permissions.xml the influence of this section is reduced when migrated to Polarion 3.0 as “GENERAL PERSISTENCE SECURITY SETTINGS” which only impacts entities like Work Items and not things like Administration.
