Migrating from an inflexible legacy system to a modern RMIS carries some inherent risks. Data conversion can be a daunting process, especially when consolidating from multiple, disparate, legacy systems to a single new platform. Risks can be largely mitigated by taking a well thought–out approach, that builds on the industry best practices and experience from previous projects.
Refer to a case study on how 4iSoft helped one of the leading providers of workers’ compensation insurance in migrating data from legacy to a modern claims management system.
Successful track-record of 4iSoft in data migration can be attributed to its foundation on 3 strong pillars – Team, Methodology & Tools.
Consists of team members with diverse skill sets – each essential for success of projects.
Conversion Subject Matter Experts – Are hands-on with leading Risk Information Management Systems (RMIS). They are equipped with deep insurance domain understanding; know the limitations of existing legacy systems and also the aware of strong capabilities on most of the new platforms.
Database programmers – Have strong skill sets across multiple database platforms – including Oracle, MySQL, Microsoft SQL and PostgreSQL.
Project Managers – Have wealth of experience in successful execution of similar projects. Their strong commitment, effective communication and adept handling of operational challenges is what sets them apart.
4iSoft takes a tried & tested approach, developed with years of experience in similar projects, fine-tuned to deliver on-time and every time.
Steps during Migration Process
Step 1 – Business Impact Analysis Requirements from various stakeholders are factored into migration planning –
- IT staff defines available network bandwidth and CPU cycle load, allowable downtime, and migration schedule
- Database and system administrators define application and database requirements
- Business owners define the importance of, and requirements for, specific applications and types of data
- Security and compliance groups define compliance requirements
Step 2 – Discovery Details about the migration hardware and software environment are collected during the discovery step. Details include current I/O workload (IOPS) on the servers, number of files/folders/volumes involved in the migration, share permissions (NFS, CIFS, or both), network configuration, DNS and AD domain information etc 4iSoft uses an automated discovery via 3rd party tool.
Step 3 – Mapping & Design During the mapping, the migration source and migration destination are identified. And mapping layout decided, choosing either of the mapping layouts – ‘One to One’ or ‘Relay Out’.
Step 4 – Creation of Migration Plan The migration plan, functions as the blueprint for the migration implementation, specifying customer expectations, defining project deliverables, and identifying migration methodologies to be used.
Step 5 – Provisioning During provisioning, the destination storage environment is prepared for the data move; LUNs, volumes, directories, and so on are allocated, security attributes are set, and shares/exports are created
Step 6 – Pre-Migration Tests Before any data is moved, it is important that some portion of the migration plan be tested and validated – in terms of timeline, migration tools used, amount of data migrated per session, and so on. Results of the migration test determine if modifications of the migration plan are warranted.
Step 7 -Migration and Cut Over This is the point within the migration process, when the source data can be moved to the destination devices. Data can be moved in two ways – Out-of-band (or out of data path) or Inband (in the data path).
Step 8 -Migration Validation For the migration to be considered complete, the validation has to be successful. This requires
- Validation of post migration environment and confirmation, that all expectations have been met prior to committing.
- Test and validate network access, file permissions, directory structure and database , through testing in non-production environment.
