moving on

I'm a little stuck... Click here to teach me more about this clue!

'upping sticks?' is the definition.
I can't tell whether this definition defines the answer.

'emotional about' is the wordplay.
'emotional' becomes 'moving' (associated in meaning).
'about' becomes 'on' (as in a book 'on' a certain topic).
'moving'+'on'='MOVING ON'

Can you help me to learn more?
