Hi Imar, 

Thank you for your reply!

By that do I need to copy the files from my "old" application's bin folder into the new application's bin folder? ..

I am not quite sure I understand :-)

I reckon DW 8.4.x.x has newer files why these should be used?

Correct me if I'm wrong :-)

Cheers,

What I typically do is make sure my application's Bin has whatever it had when it ran in production and then overwrite all those files with the ones from the latest application. That updates everything to the 8.4 version.

>> I reckon DW 8.4.x.x has newer files why these should be used?

Yes, that's why you need to overwrite all the old files.

Hi imar,

Sure helped so I actually was able to run the solution - however I am still getting the AbcPdf error. Though it must be because there is a custom module that utilizes the abdpdf.dll and that was build with an earlier version as far as my logic goes 

Yes, that might be the case. If the original project referenced or used that assembly, it may go and look for it. If you have the source code, you can check out the references of the project in Visual Studio. Otherwise, you could use Reflector and see which assemblies your custom project's assembly references and then make sure you have that file.

Hope this helps,

Imar

Hi Imar,

Yeah I do have the original source code projects - there are like 20 in total - and my resharper tells me there are multiple reference errors. I guess where it loads the dynamicweb.dll etc. must be pointed to the new application's dynamicweb.dll along with all of the "old" dll files that was locatedi n the old application folder - should be re-refered again I guess.

Yes, correct. The fastest solution is to set a Reference Path on the web project pointing to your new application's Bin folder. That updates all references for Dynamicweb assemblies to the new application. Then you need to fix the remaining references by readding the reference to the correct assemblies.

That seems to be an easier approach - I will give that a try and see if I get it sorted :-)

Thanks, Imar

Hi Imar,

I do have the csproj file for all my custom code (projects) - I do not have any sln or similar files for my application(website files). i Just copied the new Application bin's folder into the old one and replaced the old .dlls with the new ones.

The frontend does respond as well as the backend, however it seems to crash on Application Start (notification subcriber). I havent found any information on if these have changed from 8.1.xx -> 8.4

I will just scoop in here:

I suggest that you copy your custom DLLs to the new application (8.4), and then point to this folder on the IIS. It seems that ABCpdf often is quite locked and cannot be overwritten. Also, application recycle doesn't seem to release the file lock - an IIS restart is required.

So, to get the newer ABCpdf in use, just switch the solution application on the IIS.

As for your Application Start crash, there should be information in the Windows Eventviewer.

Hi Morten,

I will give that a shot and get back to you - thanks.

Hi Mikkel,

You may also need to update your web.config file as it contains some necessary changes. I typically take the one from the latest application and then insert my changes into that file.

Cheers,

Imar
