See how companies of all sizes and complexities can benefit from a new migration approach for SAP General Ledger (SAP GL). This approach seeks to reduce the activation downtime window of your SAP GL migration. Discover how to implement the migration technique over two weekends.
Key Concept

The migration to SAP General Ledger (SAP GL) can be especially challenging if companies have high transaction volumes or if their requirement is to minimize system downtime. Because the migration activities to SAP GL require users to be locked out during the data transfer process, a new technique for the migration process has been developed to minimize business disruption by using two weekends to complete the process.

The key to success for any migration project is proper planning. Migration projects have critical milestone dates that, in most cases, are not flexible. For example, you need to have several key components of the migration set up by year-end, which is a fixed time. As another example, you need to activate SAP General Ledger (SAP GL) during a time when no posting activity is allowed on the system. Often this is planned over a weekend, holiday, or some other time that is agreeable to the business community when the system is unavailable to users during the migration process. These windows of opportunity are fixed, which puts a high degree of pressure on the migration team to execute the conversion process in an efficient and timely manner.

It is essential that the planning of the migration window account for realistic processing times, contingencies, and recovery procedures in the event that a reconciliation issue arises. Establishing the correct performance benchmarks initially helps in estimating your downtime requirements and provides an early opportunity to earn the support of the business.
