Five steps for successful app modernization and legacy migration

Identify how critical the information the repurposed application would be processing, moving and storing in a legacy data migration. Assign a high, moderate, low or no rating to how critical the legacy data is.

Giving information a rating of high indicates its unavailability would have a catastrophic impact on the business. There would be loss of revenue and reputation that could not be restored, for example.

Assigning information a rating of moderate indicates its unavailability would have a serious impact on the business. There would be some loss of revenue and reputation that could be restored.

Giving information a rating of low indicates its unavailability would have a small impact on the business. There would be little loss of revenue and reputation.

Assigning information a rating of noncritical indicates its unavailability would have no impact on the business. There would be no loss of revenue and reputation.
