    Hi,

    I'm trying to migrate Sitefinity 3.7.2022.2 to Sitefinity 4.2.1650.0

    I get "Connection failed" when trying to Migrate.

    When I go to MigrationService.svc in the 3.7 site, I get this:

    [FileLoadException: Could not load file or assembly 'Telerik.Cms.Engine, Version=3.7.2136.240, Culture=neutral, PublicKeyToken=dfeaee0e3978ac79' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)]

    Damian, currently the migration module within Sitefinity 4.2 only supports updating from the latest Sitefinity 3.7 SP4 (Standard Edition), specificially the ASP.NET 4.0 version.

    The team is working to add support for the asp.net 3.5 version, but you will still need to be running the latest service pack release for 3.x before you can use the Migration tool.

    I'll make the suggestion to add this to the requirements and instructions so that it is clear this is required.

    Hope this is helpful,
    Josh

    Hi Damian,

    As Josh Morales suggested the most probable reason for your issue is that the version of Sitefinity 3.7 you are trying to migrate is not the one that Sitefinity 4.2 can work with. Please make sure you are using .Net 4.0 and the latest ( SP4 ) patch for Sitefinity 3.7 and try again. If there are updates on the status of the issue please update us so we can help you further.

    Best wishes,

    Hi
    We currently have our project running 3.7 SP4 (Community Edition). We have purchased 4.2 Standard Edition and would like to migrate. Is this possible with the Community Edition as I get the same error? Or is there something else I need to do?

    Regards
    Darren

    Hi Venketash Ramadass,

    If you use our internal build from Friday you can migrate your 3.7 Community Edition project to 4.2. Your can run the migration tool if your project is either running in .NET 3.5 or .NET 4.0. However do not forget that the build from last Friday is an internal build and is not supported officially.

    Hi

    Thanks for the response.
    Just another question. What will be the best route to proceed with migrating/updating our current project to the latest version that will be supported?

    - Thanks

    Hello Venketash Ramadass,

    You have few options:

    1. Wait for the 4.3 release ( coming in October ) which will allow you migrate your 3.7 SP4 Community edition to Sitefinity 4.3.

    2. Download the Standard Edition patch file and apply it to your website ( it is best to do it on local environment ). Then you can migrate it to the current release - Sitefinity 4.2. Later when we release 4.3, you could upgrade your Sitefinity 4.2 installation to 4.3.

    Kind regards,

    Hi Venketash Ramadass,

    Just a quick follow up. Our latest internal build supports the migration from Community Edition 3.7 SP4 to 4.x so you can try and migration process.

    All the best,
