[BlueOnyx:26162] Migration: Several NameSpace's of Users could not be set

[Colin Jack]

I'm migrating from an old 5208R to a new 5210R but am getting this error:

Several NameSpace's of Users could not be set. You might not have the PKGs for these installed: spamfilterUser

We used to have AVSpam on the old server but that was removed prior to migrating. 
Is this going to be a problem and if so what is the possible solution?

Thanks

Colin
