Project Tiptoe

Project Tiptoe was the migration of data from 4 non-year-2000-compliant Informix databases to Oracle.

These temporary tables were exact copies of the tables in the Informix databases. Several stored procedures were then written to clean up the data, e.g. translating old region codes (e.g. C0700) to new region codes (C0070000). After this was done, the data from the different tables had to be translated to fit into the new table structures in Oracle.

The number of records which were migrated can be summarized as follows:
