Over time, all software requires maintenance. It can be as simple as applying a patch or replacing a file or can be as complicated as an upgrade or migration. No matter what it is, it’s essential to keep your software current.
Usually, upgrades are handled as an “update-in-place,” which is the process of updating an existing SAS deployment to apply maintenance or add and update SAS products. The update modifies the current deployment rather than creating a new instance.
Migration in SAS terminology means creating a new SAS deployment based on an existing SAS deployment. A typical example would be migrating SAS 9.3 to SAS 9.4. Migration can also refer to taking a SAS installation from on-premise to the cloud or moving the SAS installation to a different operating system or hardware.
Zencos has been working with SAS, for over 18 years. We have installed, upgraded, and migrated hundreds of SAS installations. SAS has developed tools to streamline these processes and Zencos is adept with all of them. In addition, Zencos has developed proprietary tools and methodologies that simplify even the most difficult jobs. Regardless of whether it’s an install, migration, or upgrade, Zencos documents what has been done to capture the details and transfer this knowledge to the SAS administrators enabling them to support the new system.
