Strangely stern RAF in relocation (8)
I believe the answer is:
transfer
'relocation' is the definition.
'strangely stern raf' is the wordplay.
'strangely' indicates anagramming the letters.
'stern'+'raf'='sternraf'
'sternraf' with letters rearranged gives 'TRANSFER'.
'in' acts as a link.
(Other definitions for transfer that I've seen before include "Move from one team to another" , "Change to another group or surface" , "Bring over" , "Convey from one place to another" , "Footballer maybe" .)
