Upgrade Approach
Most large organizations have many independent or semi-independent OpenROAD applications. Usually the same end users are running these applications. In other cases, independent groupings of end users are running applications. Some organizations also use multi-tier architectures using the OpenROAD Server.
These situations raise the question of whether separate applications running different OpenROAD image versions can be upgraded independently.
Observe the following guidelines when you are considering selective upgrading of OpenROAD applications:
• Dual development environments are required for OpenROAD 4.1 and OpenROAD 5.1.
• Running OpenROAD 4.1 images using OpenROAD 5.1 runtime is not supported.
• Running OpenROAD 5.1 images using OpenROAD 4.1 runtime is not supported.
• If you are using OpenROAD Server, you must upgrade it at the same time as the OpenROAD clients.
If your OpenROAD installation is complex or sizeable, these considerations emphasize the need to plan your upgrade project to OpenROAD 5.1.
