The software will manage some 4,000 units located across all Aston hotels, condominium resorts, villas, and cottages.
According to Micros, the OPERA Enterprise software includes the OPERA property management system (PMS) to manage the daily tasks of each property, and the OPERA revenue management system (ORMS) to manage reservation activity.
It also includes the OPERA vacation ownership system (OVOS) for condo properties and the OPERA web suite for online reservation capabilities for condo owners.
As Aston has several agreements with condo owners, the new Aston Hotels & Resorts online portal can be used by them to book their own unit, access their profile and view statements online.
Aston Hotels & Resorts president Kelvin Bloom said that the company sought to deploy the latest technologies customised for its hotels and condominium resorts.
"Micros brought an integrated platform that could adapt to our current needs and portfolio expansion plans," he said.
