Sergey Dmitriev and Gergely Cserdi, Amazon Web Services
Summary
This pattern describes how to migrate an SAP Adaptive Server Enterprise (ASE) database from an on-premises host to an Amazon Elastic Compute Cloud (Amazon EC2) instance. The pattern covers the use of AWS Database Migration Service (AWS DMS) or SAP ASE native tools such as ASE Cockpit, Sybase Central for ASE, and DBA Cockpit for migration.
Prerequisites and limitations
Prerequisites
An active AWS account
An SAP ASE source database in an on-premises data center
Limitations
The source database must be less than 64 TB
Product versions
SAP ASE version 15.x and 16.x or later
Architecture
Source technology stack
On-premises SAP ASE database
Target technology stack
SAP ASE database on an EC2 instance
Database migration architecture
