Translations:Upgrading from a previous version/12/en
From LimeSurvey Manual
Special checks after an upgrade:
- From a version earlier than v1.53: When upgrading from a version before v1.53 to the latest version, please check the global user rights of each user. There was a new superadmin right introduced in v1.53 that can give a user the same privilege as the master administration account created during the install. The upgrade script is guessing to whom this permission should be given in the older versions. As this is not perfect, it should be carefully checked.
