A technician is migrating a customer's system from AWFO V15.

According to the Avaya Workforce Optimization Select Migration Guide, the side-by-side approach is a migration method that involves installing a new Avaya Workforce Engagement system on a separate set of servers, and then transferring the data and configurationfrom the existing AWFO system to the new system. Some of the factors that led to this recommendation are:

B. It will support rollback by reverting to the 15.1 Data Center. The side-by-side approach allows the customer to keep their existing AWFO system intact and operational until they are ready to switch to the new Avaya Workforce Engagement system. This means that if there are any issues or problems with the new system, the customer can easily revert to the 15.1 Data Center by changing the DNS settings and restoring the database backups.

C. It will minimize upgrade downtime risks. The side-by-side approach reduces the downtime risks associated with upgrading the system, as the customer can perform most of the migration steps in parallel with their normal operations. The customer can also schedule the final cutover to the new system at a convenient time, and avoid any disruption to their service levels or customer experience.

The statements A and D are incorrect because:

A. It is suitable for small systems only. This is not true, as the side-by-side approach can be used for any size of system, depending on the customer’s preference and resources. The side-by-side approach may require more hardware and software licenses than the in-place approach, but it also offers more flexibility and reliability for the migration process.

D. The data on the source DC servers are reformatted with Windows Server 2016, and installed with R20.X. This is not true, as this describes the in-place approach, not the side-by-side approach. The in-place approach is a migration method that involves upgrading the existing AWFO system on the same set of servers, and then applying the R20.X installation on top of it. The in-place approach requires reformatting the source DC servers with Windows Server 2016, which can result in data loss or corruption if not done properly. References: Avaya Workforce Optimization Select Migration Guide
