Upgrading Schema Holders
If you have prior version schema holders and want to take advantage of current Progress version features, make the following preparations before using the Version 9 DataServer:
- Start the version of Progress with which the schema holder was created, then connect to the schema holder.
- 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.- Start current version of Progress.
- Create and connect to an empty Progress database.
- From the Data Admin main menu, choose Admin
Load Data and Definitions
Data Definitions (.df).
- Type the name of your
.df
file, then choose OK.The utility loads the
.df
file into the schema holder.- Use the Verify Table Definitions DataServer utility to verify the data definitions in the schema holder.
- Recompile your r-code against the new schema holder.
