For a successful migration overall, obtain a basic understanding of the CCL
language. See the
CCL Programmers Guide before performing
any conversions.
Note: Data models containing joins should be recompiled
when migrating from ESP 5.0 to any subequent version
of the product. Failure to do so may prevent the compiled data model from being
loaded by the server. In the case that the model does load, the results produced will
be incorrect.
