Securities accrued fee migration from Legacy to Transact

Hi Team,Could you please assist with the following query?We are currently performing a data migration from the Legacy system to the Transact system, and the migration is scheduled to occur mid-cycle within the quarterly fee cycle (every 3 months). This results in one month of accrual in the Legacy system and the remaining two months in Transact.Our goal is to post a single consolidated Securities Fee entry to the customer account at the end of each quarter, combining both Legacy and Transact accruals.In the Transact system:

• Accruals are calculated in SC.SAFEKEEP.ACTIVITY
• At quarter-end, the system posts two months of accrual into

  SAFEKEEP.HOLDING

  .

We would like to include the Legacy system's one-month accrual in this samebucket to ensure a single fee entry is posted to the customer's account.Is there a way to incorporate the Legacy accrual fee into Transact for this purpose?
Are there any available options or best practices to handle this scenario?Thank you.
