If you have prior version schema holders and want to take advantage of current OpenEdge version features, you must prepare the schema holder before using the Release 10 DataServer.
To prepare to update a schema holder:
1. Start the version of OpenEdge with which the schema holder was created, then connect to the schema holder.
2. Dump the data definitions (.df file) from the schema holder and move the .df file to the new client machine, if necessary. Dumping and loading a .df file is the only way to preserve any information that you might have added to the schema, such as display formats, help strings, and validation expressions.
3. Start the current version of OpenEdge.
4. Create and connect to an empty OpenEdge database.
5. From the Data Administration main menu, choose Admin > Load Data and Definitions > Data Definitions (.df).
6. Type the name of your .df file, and click OK.
The utility loads the .df file into the schema holder.
7. Use the Verify Table Definitions DataServer utility to verify the data definitions in the schema holder.
8. Recompile your r-code against the new schema holder.
