Phased Implementation

You can phase in the upgrades for any release. It is not necessary to upgrade all CA Gen products simultaneously. When you phase in the upgrades, the following general guidelines apply:

• Upgrade the encyclopedia first. Check in all models before upgrading the encyclopedia, including models and subsets checked out to Workstation Toolsets and to other encyclopedias. After the upgrade completes, check out the models you need.
• When the schema level changes, you convert existing models on the encyclopedia before downloading them to the new Workstation Toolset. If the encyclopedia includes models in schema levels that are not supported in the new release, convert or delete these models.
• A Workstation Toolset only supports models at a single schema level.
• The Implementation Toolset must be at the same or a newer release as the Build Tool, primarily because of the runtime routines the generated code expects.
