Your address can be changed in the company archive (COM). 
This is where the invoice address is picked from. JHC consultants have the access to update this.

The location archive (LOC) has to be updated too.
The Print and IP addresses should be checked that they work as they should when moving.

Changing the address in the company archive (COM) will not update the address on closed documents (ST:9), but new documents will have the new address.
