Has anyone done upgrades from DNN 3.1.1 to DNN 4.3.6 with custom modules included?  (Not third-party or commercial modules -- these modules were written by my predecessor, in VS2003 and DNN 3.1.1, and I have zero support on them.)

I've been given the source code for a DNN 3.1.1 website (including SQL Server 2005 database and installation files - it has several custom modules -- not commercial).  I have to upgrade to DNN 4.3.6.  (no choice -- employer's decision)

In preparation, I've created a new database, a new site in IIS 5 and ASP2, and installed the Source version of DNN 4.3.6.  Now comes the fun part -- and the questions.

I know I need to install all DNN modules (well, the site uses all but 2).  Next I need to install the custom modules.  Now -- these are written in Visual Studio 2003 -- does this mean that to install them I need to use the Module Upgrade Wizard?  What glitches will I need to look for in converting these files?  Once I've used the Module Upgrade Wizard can I open the whole thing in VS 2005? 

I know that once the modules are in there, I'll need to copy my production database data into the new db and modify the web.config. 

Will this take care of the portals that were created in the original site, too? 

Am I missing anything else?

All answers are greatly appreciated!
