Translations:Upgrading from a previous version/10/en

Special checks after an upgrade:
 * from any earlier version to 2.xx: Proper question codes are mandatory now. After upgrading the installation, check the survey logic of all surveys and correct the codes where necessary
 * 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
 * from any earlier version to v2.06: From 2.05 to 2.06, some unused permissions when editing global permissions for 'surveys' were activated. For example, if a user had only the 'create' permission in 2.05, the other permissions located to the right of 'create' would also get activated with the update to 2.06 (View/read, Update, Delete, Import, Export). Please check whether the admin users got any other global permissions besides the 'original' ones after the update. If yes, please edit them accordingly
