I had a small error during the upgrade (ie site still seems to work fine)...

/* correct any File folderpaths which do not match the value in the Folders table */
update dnn_Files
set    Folder = FolderPath
from   Folders
where  Files.FolderID = Folders.FolderID
and    Folder <> FolderPath 

It looks like the object qualifier doesn't exist on the "folders" object.

So, should I just rerun this from host > sql as:

update dnn_Files
set    Folder = FolderPath
from   dnn_Folders Folders
where  dnn_Files.FolderID = dnn_Folders.FolderID
and    Folder <> FolderPath

 ?

Or is there another solution? I've had enough problems in the past that I don't always jump at what seems to be the obvious solution -- at least before seeking consensus.

(and funny that this table is the one giving me problems -- as in my previous upgrade

Just coincidental ... I hope.)
