Data is crucial in any type of legacy migration process. During the data migration, extreme care must be taken, as data blocks may be missed or deleted. If the loss is pertaining to critical business data, then the company may face huge losses. The severity of damage due to data sensitivity issues is purely based on how critical the data is.
In the rush to get migrated, most of the times companies make use of primitive tools. The migration performed by such tools leave vulnerabilities for hackers to exploit resources. So, to conduct secure and smooth migration it is essential to define well-designed procedures and make use of robust tools that are functionally specific.
To ensure secure access to data, the storage and retrieval process involves encryption and decryption. This involves usage of customized hybrid encryption algorithms to ensure maximum security. The migration of such encrypted databases, if not properly done, would clutter up the data and ultimately lead to data corruption and data loss.
Prior to performing the migration, get a detailed understanding of systems framework to be migrated and plan interfaces to conduct smooth migration.
To test the migration process, it is advised to develop an Automated Test Framework. This acts as a signboard in running the test process to test and fix the issues in timely manner.
The strong security policy defines the direction and respective activities the migration accomplishment teams need to abide by. This acts as a guidepost to the team in handling the data better and offers a better understanding on current as well as evolving threats.
