I hit the same issue. I went back to retest and now I'm hitting the issue on the test database, where I didn't hit it before...

I'm trying to track down if anyone else knows about this. I can't find anything so far. I think we're going to have to open an issue on Connect. I just did a few searches there. There doesn't seem to be anything. This is either a bug, or we're missing something. I'm just confused by how I got it to work before.

I posted it to Connect:

You can vote on it, set the priority, add your comments, especially since this is your issue.

I'm going to keep hacking at it as time allows.

Nuts. I might have been premature in posting to Connect. I finally found another reference:
https://connect.microsoft.com/SQLServer/feedback/ViewFeedback.aspx?FeedbackID=351548&wa=wsignin1.0

I'm testing removing the certificate now.

Nope removing the certificate didn't fix the issue. That makes me feel better. There must be an alter database statement that removes the reference to encryption.

I think that's worth noting. Now we know it happens on two platforms. If there's a way to fix it, we should find out, I hope. I also blogged about it and sent out a tweet. Hopefully someone with an answer will notice.

If we analyze the error from backup command. It is complaining about log file. So I thought how about trying to attach just MDF file but it failed.

sp_attach_single_file_db @dbname = '[TDEDisabling]', @physname = 'J:\Backups\TDEDisabling.mdf'

Msg 33111, Level 16, State 3, Line 1
Cannot find server certificate with thumbprint '0xBB1B0816079C10A6342683443A8E576196EFBE73'.
Msg 1813, Level 16, State 2, Line 1
Could not open new database '[TDEDisabling]'. CREATE DATABASE is aborted.

I know this thread is over a year old but I'll post in case someone else runs into this problem.

I've run into the need to know how to remove TDE. In doing my research I came across this thread and some other links with similar issues. The blogs say that setting encryption to off isn't enough. You also need to drop the database encryption key. Only after performing these two steps can you create a fresh backup of the database and restore it to a new server without encryption.
USE MASTER
GO
ALTER DATABASE DBNAME
SET ENCRYPTION OFF
GO
USE DBNAME
GO
DROP DATABASE ENCRYPTION KEY
GO
