No, sorry I did not.  My solution was to spin up another server and install 6.0 from scratch.  Now I'm going through the tedious process of migrating each website by hand (since the template function seems to blow up when loading a 5.X template).  Needless to say, I'm less than amused by this whole process.

Cheers,
TIm

Excellent! That fixed it for me too :-)  Great, that takes the pressure off moving the websites quickly to the new server.  Now if only I could get export/import to work properly... oh well, you can't have everything.  (where would you put it?) LOL

Cheers,
Tim
