I want to upgrade a v3.1.1 site using the recommended upgrade path suggested by the wiki here, but I only see an install zip.  Should I use this or is there an upgrade zip located elsewhere?  Any help is greatly appreciated!

Thanks, I found the install packages there and have been using Mitch Sellers guide and with some advice from Rob Bryn I have successfully got my 3.1.1 site to 3.2.2....BUT...when I tried to upgrade to 3.3.0 I was unable to log in.  All of my passwords failed. I tried to restore all the way back to the original version, also restored my database, and nothing worked.  If anyone has any idea or experience with this I will be all ears.  

Thanks ahead of time for any help,

The machine key, decryption key, and all the sql data match with what I had in the original sites web.config.  I wrestled with it for a few more hours and just restored my vm to its previous state.  So I'm going to try again.  I'll be posting back here if I encounter more issues. I have seven more sites that are at 3.1.1 and they all have to be upgraded, fun stuff.  The first time is always the hardest, at least I hope so.

Thanks for the help,
Stephen Gregg
