These are the other things you need to make sure you copy over. If your web.config file is older however, as in it was from dotnetnuke 1 or 2, it wont have the keys or anything in it (which could explain why you didnt see it, they just added that stuff when they began naming the file 'release.config' by default), and you dont have to worry about them until you upgrade (like to 3+ or 4), then make sure you copy all of the information over.

<add key="SiteSqlServer" value="Server=7.8.2.1,23;Database=audio32xT;uid=Myuid;pwd=usm38fTJ;" />

<add key="MachineValidationKey" value="DB02CB97BAE1814E49F1310895EC33B22FC70014" />

<add key="MachineDecryptionKey" value="6E324A6FF2B87D590B71D61FDD95C82A137C980893117CF0"/>

<add key="InstallationDate" value="11/19/2005" />

If you have made any further changes to your web.config file for third party modules,  HTTP compression, or database object qualifiers, copy these changes across to the release.config file

If you have enabled HTTP compression, disable it until you have completed the upgrade

Okay, I threw caution to the wind and did what you suggested.  I copied the stuff from web.config to release.config.  I renamed both files and reloaded site.  It came up okay.  But that did NOT fix my File Manager problem.  The page still loads with errors.  AND now I can't upload anything to my site.  I tried uploading a .doc file and as soon as I clicked "Upload Selected File" by browser displayed an error page that said Can't Load Page or somethint to that affect.  (the normal browser error message you get when you type in a non-existent URL).

Anyone have any ideas on how to get the file manager to work properly?  I'm using DNN 3.2.2.
