Upgrade help...

Using Umbraco And Getting Started

Umbraco 7
Trying to upgrade from 7.12 to 7.15.6...

I'm getting this error:

The type 'Umbraco.Web.UmbracoApplication' is ambiguous: it could come from assembly...\umbraco.dll ... or ... umbraco.web.dll

The code that's throwing the error is on global.asax
```
<%@ Application Inherits="Umbraco.Web.UmbracoApplication" Language="C#" %>
```
I understand the error, but i'm not sure how to fix it.

Thanks @BrendanRice for your reply. Unfortunately the thread you linked to suffered from a different issue than mine. The solution for the thread you linked to was changing the Target .NET version from 4.7.1 to 4.7.2 My project is already targeting 4.7.2

How did you go about the upgrade, what steps did you do?

My old Umbraco 7.12 wasn't in visual studio...

So I created a blank 4.7.2 .NET site in Visual Studio and copied all of the files from my Umbraco 7.12 site into that blank project.

Then I ran nuget and installed 7.15.6

Try to run the site in debug and I get the above error.

Maybe something went wrong with the process of creating the VS solution?I've done the same thing before to get sites into VS.

The steps I take are (from the top of my head)
1. Create blank VS ASP.Net MVC porject
2. nuget the same version as the old site:
  
  Install-Package UmbracoCms -Version 7.12.0
3. Copy the files from the old site (excluding the Bin & Umbraco folders)
4. Run the site to make sure it works
5. I then upgrade using nuget to each major release making sure to check any breaking change in the changelog

Good luck, also take backups at stages in between each major release upgrade in case you find something broken.

I did as you suggested. New blank .NET 4.7.2 project. Install Umbraco 7.12 Copy in everything from my 7.12 site (except bin and umbraco folders)

I hit this error on the first debug...

Any idea?

It looks like a web.config issue. If I remember correctly they removed MySql support in later versions of Umbraco and it seems like the web.config still references it.

Instead of copying over the web.config try to keep the original and copy in the parts you need i.e. connection string , app settings.

Thanks again @BrendanRice. I wondered about that when I copied it in. Boom. Ok. I've got 7.12 stood up. Time to stepwise upgrade. Thanks for your help Brendan!

Well no build errors in 7.12, When it runs it takes to me to the login page for Umbraco. But, when I login it takes me right back to the login page.

Here's the URL when I debug: http://localhost:54794/umbraco/AuthorizeUpgrade?redir=%2finstall%2f%3fredir%3dtrue%26url%3dhttp%253a%252f%252flocalhost%253a54794%252f#/AuthorizeUpgrade?redir=%2Finstall%2F%3Fredir%3Dtrue%26url%3Dhttp%253a%252f%252flocalhost%253a54794%252f

It's an infinite loop.

I've tried modifying the url to: http://localhost:54794/umbraco or http://localhost:54794/

But both redirect to the AuthorizeUpgrade url above.

Are you sure the connection string is correct?

hmm maybe it's the umbracoConfigurationStatus. What does it say in the web.config app setting for this key?

<add key="umbracoConfigurationStatus" value=""/>

The connection string looks good. I switched it from a database on a SQL server to a local SQLCE database.

<add name="umbracoDbDSN" connectionString="Data Source=|DataDirectory|\Umbraco.sdf;Flush Interval=1;" providerName="System.Data.SqlServerCe.4.0"/>

I tested changing it to
```
<add key="umbracoConfigurationStatus" value="7.12"/>
```
Same experience with the infinite loop on the login page.

The connectionstring was good the SQLCE was bad. I recreated it and i'm good to go now (I think). Thanks for all your help!!!

Hi bh

In your fresh new Web. Config for 7.12 make sure your umbraco users membership provider entry is the same as in the Web. Config for the existing site... Particularly if you had a setting for uselegacyencoding that was previously set to true... Basically your fresh new web.config will be trying to validate your login password with a different hash to your existing site preventing you from logging in if that setting is different...

Regards

Marc
