Well , It worked for me. Just read carefully the release notes http://docs.orchardproject.net/Documentation/Orchard-1-4-Release-Notes
In my case I´m working with full source code enlistment so the latest version was already in my computer.
But in order to get my settings and data from my
old Orchard project (1.3, not enlistment using any source control )
I had to copy:
- "App_Data" folder (settings are inside this folder, even your DB connectionstring)
- "Media" folder
- All own "Modules" or third-part ones folders
on the 1.4 source code.
Then, create in your web server a web application in order yo access it using the browser.
>> Remember to access the first time appending "/admin" to the URL
where the home page should be
Next follow the instructions in release notes.
