Buffer Copy Conversion
The buffer copy closely follows the protocol of prior conversions, but uses the faster, more efficient buffer copy method to transfer existing production data from the source to the target databases. The prior method used a dump and load technique.
The buffer copy method has an advantage over in-place: You create new target production databases, and, therefore, can edit the database structure files to take full advantage of the Progress OpenEdge database deployment technology. This typically results in a more efficient, more easily managed database.
Note: If your source database is MFG/PRO eB or later, you may already have taken advantage of database storage areas, making this rationale for using the buffer copy method less important.
