Install new version in parallel to existing installation
As an alternative to the setup, you can perform the update by installing the latest ARIS version in parallel with your existing ARIS installation on a different server. If you use an Oracle or Microsoft® SQL Server as the database management system (DBMS), you must create the ARIS Risk and Compliance database schema. In addition, you must create the tenant schema of ARIS Risk and Compliance. For detailed information, refer to Installation of an Oracle or a Microsoft® database and to Add tenant schema of ARIS Risk and Compliance (in the Technical help of the ARIS Risk and Compliance online help > Installation or in the ARCM - Installation Guide.pdf)
