Moved up prior to creating miscellany (9)
I believe the answer is:
potpourri
'miscellany' is the definition.
(I know that miscellany can be written as potpourri)
'moved up prior to' is the wordplay.
'moved' is an anagram indicator.
'up'+'prior'+'to'='uppriorto'
'uppriorto' anagrammed gives 'POTPOURRI'.
'creating' is the link.
(Other definitions for potpourri that I've seen before include "Scented petals and spices" , "Perfuming mixture" , "Petals and spice mixture; medley" , "Fragrant mixture" , "Mixture of petals and spices for perfume" .)
