Open Source surgery: Migrating from UNIX to Linux
Legacy systems are always going to be an issue that can cause organisations a massive headache. You can’t just get rid of them: they may contain data and involve systems that are invaluable. Migration needs to be handled carefully. If your organisation is in the banking and financial services sector, then it is even more critical to manage end-of-life systems delicately; to comply with the increasing amount of legislation and regulations (predominantly surrounding data management and record-keeping).
Problems are typically caused by:
- A lack of planning and testing of the target environment, the migration of data and the migration of functions
- A lack of skills and knowledge in the target environment and a lack of ongoing management
- A lack of experience of managing transitions such as this
- Resistance to change from within the organisation
