The last three parts of our conversion blog (see all of the posts here) go hand-in-hand and require the most time on the project plan. Development - During development of the conversion routines, you may want to consider using error handling standards based on corporate standards. This is where data

Cracking the code to successful conversions: Decommission plan
I have a rule – any conversion or upgrade will require the creation of a decommission plan. A decommission plan should include the following: A list and definition of each database, table and column (source and target). A list and definition of each of the current programs in use (you
Cracking the code to successful conversions: Physical data models
The physical data model should represent exactly the way the tables and columns are designed in the in the database management system. I recommend keeping storage, partitioning, indexing and other physical characteristics in the data model if at all possible. This will make upkeep and comparison with the development, test
