Accounts receivable and payables Take on process

We have a client who currently have a company in sage 300 but now they would like to split some of their vendors and customers to a separate company in sage 300. They would like to have take on balances for the vendors and creditors and also to show the current ageing on vendors and customers in the new company.

i would like to understand the process to take on the balances and the ageing from the old company to the new company
