Data migration
Post-migration: After data migration, results are subjected to data verification to determine whether data was accurately translated, is complete, and supports processes in the new system. During verification, there may be a need for a parallel run of both systems to identify areas of disparity and forestall erroneous data loss. Additional documentation and reporting of the migration project is conducted, and once the migration is validated complete, legacy systems may also be decommissioned. Migration close-out meetings will officially end the migration process.
Colocation (business)
Colocation (or co-location) is the act of placing multiple (sometimes related) entities within a single location.Colocation is often used in the data sourcing industry to mean off-site data storage, usually in a data center. This is very important for businesses since the loss of data can be crucial for companies of any size, up to and including disciplinary action for employees or loss of their job. An unexpected loss in data can result from fires, earthquakes, floods, or any sort of natural disaster.
