Typically, the data migration process is not carried out on the production
system first. It is important to carry it out on a test system and repeatedly
revise the business rules until all the data has been migrated completely
and accurately. Depending upon the complexity of data migration, this
process may take anywhere from weeks to months.
After the migration results in the test environment are satisfactory, together the team decides a cut-off date for actual data migration. At the cut-off date, the migration is performed on the production system.
xFusion Studio makes it easy to repeat the data migration process. As all the logic of data migration has already been captured in the Fusion packs, it is just a simple matter of editing the Fusion packs to point to the new destination and running the migration unattended.
