Version specific upgrades

    For now, this document will only list updates from the past two years, but it will eventually be improved to go further back.

    Most of the time you will be able to upgrade directly from your current version to the latest version. Follow the steps in the general upgrade guide, then these additional instructions for the specific versions. (Remember that new config files are not mentioned because they are already covered in the general upgrade guide.)

    Version 6 to 7.0.0

    Read and follow the full v7 upgrade guide

    Version 7.0.0 to 7.0.1

    • Remove all uGoLive dlls from /bin
      • These are not compatible with V7
    • Move appSettings/connectionStrings back to web.config
      • If you are on 7.0.0 you should migrate these settings into the web.config instead of having them in separate files in /config/
      • The keys in config/AppSettings.config need to be moved back to the web.config section and similarly, the config/ConnectionStrings.config holds the Umbraco database connections in v7.0.0 and they should be moved back to the web.config section.
      • /config/AppSettings.config and /config/ConnectionString.config can be removed after the contents have been moved back to web.config. (Make backups just in case)
    • Delete all files in ~/App_Data/TEMP/Razor/*
      • Related to issues with razor macros

    Version 7.0.1 to 7.0.2

    • There was an update to the /umbraco/config/create/ui.xml which needs to be manually updated, the original element had this text:

      <nodeType alias="users">
            <create assembly="umbraco" type="userTasks" />
            <delete assembly="umbraco" type="userTasks" />
      • The <usercontrol> value has changed to: /create/user.ascx, this is a required change otherwise creating a new user will not work.
    • There is a breaking change to be aware of, full details can be found here.

    Version 7.1.0

    • Remove the /Install folder.

    Version 7.2.0

    • Copy in the /Views/Partials/Grid (contains Grid rendering views)

    Version 7.3.0

    Make sure to manually clear your cookies after updating all the files, otherwise you might an error relating to Umbraco.Core.Security.UmbracoBackOfficeIdentity.AddUserDataClaims(). The error looks like: Value cannot be null. Parameter name: value.

    NuGet will do the following for you but if you're upgrading manually:

    • Delete bin/Microsoft.Web.Helpers.dll
    • Delete bin/Microsoft.Web.Mvc.FixedDisplayModes.dll
    • Delete bin/System.Net.Http.dll
    • Delete bin/System.Net.Http.*.dll (all dll files starting with System.Net.Http) EXCEPT for System.Net.Http.Formatting.dll
    • Delete bin/umbraco.XmlSerializers.dll
    • In your web.config file, add this in the appSetting section: <add key="owin:appStartup" value="UmbracoDefaultOwinStartup" />

    Other considerations:

    • WebApi has been updated, normally you don’t have to do anything unless you have custom webapi configuration:
    • MVC has been updated to MVC5
    • It is not required that you merge the changes for the Examine index paths in the ExamineIndex.config file. However, if you do, your indexes will be rebuilt on startup because Examine will detect that they don’t exist at the new location.
    • It's highly recommended to clear browser cache - the ClientDependency version is automatically bumped during install which should force browser cache to refresh, however in some edge cases this might not be enough.

    Version 7.4.0

    For manual upgrades:

    • Copy the new folder ~/App_Plugins/ModelsBuilder into the site
    • Do not forget to merge ~/Config/trees.config and ~/Config/Dashboard.config - they contain new and updated entries that are required to be there
      • If you forget trees.config you will either not be able to browse the Developer section or you will be logged out immediately when trying to go to the developer section
    • You may experience an error saying Invalid object name 'umbracoUser' - this can be fixed by clearing your cookies on localhost
