Need Help in Coming up with the best solution for this scenario

The acquisition of Scotiabank's assets by Belize Bank was first announced in June 2020. Central Bank of Belize conducted a thorough review of the purchase agreement between the bank and Caribbean Investment Holdings Limited, an Ashcroft Alliance. This involved a payout of about US$30 million for Scotiabanks assets. The acquisition of the bank became possible when Scotia decided to leave the country. In an interview with Executive Chairman of Belize Bank Ltd, Lyndon Guiseppi, in June 2020, he said that following such announcement, they engaged in discussions with Scotiabank for months before making a deal. The acquisition gives birth to the largest commercial bank holding in Belize, under the Ashcroft Alliance. As the changeover takes its course, it appears that the current staff need not worry as a message sent to customers on the acquisition states that all current Scotiabank employees will remain with the company. As the head of the HR department for Belize Bank, you:

• Reviewed compensation and adjusted salaries for the sake of fairness. Communicated this to all affected employees.
• Developed job requirements for current and new jobs.
• Had each old and new employee fill out a skills inventory Excel document, which has been merged into a database.

From this point, you are not sure what to do to fully integrate the new organization. Which components of your HR plan will you have to change?
