Migration Guide : Migrating from Version 5.0 : Changes in Server Workbench
Changes in Server Workbench
Smalltalk Server, the runtime environment for deploying server applications, is included with VisualAge Smalltalk Server Workbench in VisualAge Smalltalk V6.0 and VA Smalltalk. This means that all of the code required to deploy server applications is included as part of Server Workbench and it is no longer necessary to install this feature separately.
The deployment environment for Server Workbench is not backward compatible with Server v5.0 or earlier. This means that applications packaged on Server Workbench V5.0 or earlier will not run on the redistributable files for Server Workbench V6.0 or VA Smalltalk. To enable your V5.0 or earlier application to run on a V6.0 or VA Smalltalk system, repackage your application using the current version of Server Workbench.
If your systems need to run applications packaged from both releases, keep Server Runtime V5.0 installed in parallel with the current version of Server Runtime on those systems.
