I originally posted this here but decided to repost here also because I believe this to be a real timesaver.
I ran into it. You probably did too. You tried to convert your BizTalk 2006R2 solution to BizTalk 2010 (or 2009) and found that your solution was OK, your C# libraries went just fine, but none of your BizTalk projects had been converted.
Then, when you retried this from the converted solution, or tried to load a .btproj directly, you got that dreaded message: Error converting project file. The element <BIZTALK> beneath element <VisualStudioProject> is unrecognized.
I 'blame' the BizTalk Deployment framework for this as Microsoft clearly thought no-one would ever try to move away from the suggested Deployment and Development build configurations. So if you, as we did, change it to Debug and Release when we moved to the BTDF, you are in for a bit of work.
Now I have for you the best way to get going. I found it just out of sheer desperation trying to get things working the way they should.
The best part? It takes just about 5 minutes per solution, independent of the size of it!!. It has worked for all solutions I have tried so far.
Now, How to do it.
1) Make sure you have a backup of your solution file BEFORE trying any conversions. You need the clean 2006R2 version (or : you can of course also use an Undo Pending Changes option of your TFS when the time comes to revert the solution file in step 7).
2)Just open the solution in Visual Studio 2010 as you want to. This will prompt the upgrade wizard to do what it does best.
3)Review the loaded solution. You should have a converted solution, loaded C# libraries and unloaded BizTalk projects.
4) Close all windows in Visual Studio.
5) Right-click each unloaded project file and select Edit to open it in text mode. You now should have all files open in text mode.
6) Using basic search and replace do a replace on all open documents replacing Name = "Debug" by Name = "Development" and replacing Name = "Release" with Name = "Deployment". Each replace should give a count of items replaced equal to the number of open BizTalk projects.
7) Now the big trick: Either close your solution and put back the backed up .sln file you made earlier and then re-open your solution OR just select Undo Pending changes on your solution file (AND JUST THE SOLUTION FILE...)
8) The Migration Wizard will trigger again and now will convert your BizTalk projects as expected.
9) Now we are almost done, except that you BizTalk project has a configuration base (Deployment/Development) that has not been defined in the solution (Release/Debug).
You need to get this back in sync. To do this, unload all BizTalk projects from the solution (right-click, select unload) and once again open them in textmode (all other windows closed)
10) Now reverse the replace: replace "Development" with "Debug" and replace "Deployment" with "Release". Save all files, then close all files.
11) Close and reopen you solution, as for some reason, Visual Studio complains about reloading projects that are already opened under the solution if you try to reload them now. Even when they are closed...
12) Reload all BizTalk projects in the solution, save and we are done.
So. I hope this just will get you going. Any comments, as always, are appreciated to make this work better, make note of exceptions to the rule etc etc.
