Deploy new & migrate existing
Now we can deploy and bed down our new process, assuming it is ready. If not, we can start by migrating an appropriate process.
The first process selected for migration should be either fairly simple and widely used, or a more complex system with a smaller user base. The larger the system, the more work will be required, so do not choose too large an initial system. Bear in mind that no changes should be applied to the version 7 system while this is going on, lest we are forced to re-apply those changes to the version 9 system.
This system will have to be updated and developed on a separate development and/or UAT environment, of course. Once complete and tested, the migration of the existing data can be made, and the new version 9 solution deployed.
During this exercise, we may wish to re-examine many of the design choices of previous development. The new abstraction of database queries to Business Objects, and Database (and other) connections to Connectors, may give us much more latitude and scope to combine functionality. This may make each subsequent conversion faster, as less code needs to be written as well as our knowledge increasing.
