We are sorry to hear you have problems with the upgrade. Here are answers to your questions:
What file do you download to do the upgrade?
You can choose between two Sitefinity Standard installations: for .Net framework 2.0 and 3.5 .
Also, you could choose from two possible ways of how to upgrade - by adding your changes to a new Sitefinity 3.6 project or by applying a 3.6 patch to your existing 3.5 project. For either choice, a very good document to follow in the process is this: Upgrade Instructions .
have downloaded the patch for 2.0 - are you sure your previous project
was running on 2.0? If not (if it was running on 3.5), you need to
. The error you are getting is exactly because of this - the assemblies you have copied from the patch are not for framework 3.5 and that is why they can't be located:
Could not load file or assembly
'System.Web.Extensions, Version=188.8.131.52, ...
Text File Error
The text file upgrade_3_6_templates.txt is important - it will upgrade the templates in your database so that there are no errors that Sitefinity is not able to find specific templates. That is why it is important that this file is exactly in App_Data folder.
You will need to put it back and provide permissions for the text file so that it will run. When it does run, it will be deleted automatically.
My recommendation is, if possible, to download the 3.5 patch and do a
clean upgrade of your Sitefinity 3.5 project. If not, after you put back the text file and you make sure the permissions are correctly set, run your application. There is a possibility that the text file is not run automatically since you removed it. If this is the case (if the file is still in the App_Data folder), you will need to manually make sure the text file is run.
To do that, you need to
open the database for the project, open the table sf_CmsVariables
, and check if SchemaVersion has the value 1870. If yes, change it to a previous number, say 1800. The next time you run your project, this will make sure the database is upgraded again and the text file will run automatically, then be deleted. You will know if this has gone successfully when the file is no longer in App_Data
The cause of this error is the same as the previously explained Assembly error. The fix is the same as well.
Let me know if this does not help and you need further assistance.
