Sub Module attaching to Contact when a Lead is converted

I don’t think I have found anywhere in the Community that covers this but please point me at it if it is covered

I have made Notes against a Lead
When the Lead becomes a contact I would like those completed notes to move across and attach to the Contact.

If this is possible I would then like to do the same with a new customer module connected to a Lead - moving to the Contact.

TIA

Tony
