How can you prepare for a large-scale operating system migration?

80% of the success / result is planning, planning, planning. Good plan must include roles and responsibilities, time schedule, conditions when you will roll back / stop migration if unexpected situation will happen. And do / plan dry runs / test runs as part of plan, to understand time / resources expectations

To prepare for a large-scale operating system migration by creating a detailed migration plan with clear objectives. Compile an inventory of systems and applications, ensuring compatibility with the new OS, and implement a robust backup and disaster recovery strategy. Conduct pilot tests to identify and address any potential issues, while providing training and regular communication to stakeholders. Execute the migration according to plan, closely monitoring progress and resolving any issues promptly. Validate the migrated systems, provide ongoing support, and document the entire process for future reference and improvement.

You have to know where you are before where you are going. Assessing your current infrastructure and inventory will be critical to knowing what gaps you have as you look to innovate your technology for the future.

Prepare for a large-scale operating system migration by conducting a comprehensive inventory of current systems and applications. Develop a detailed migration plan, including timelines and resource allocation. Test the migration in a controlled environment to identify potential issues and refine the process. Communicate transparently with stakeholders about the upcoming changes, providing training and support resources. Establish contingency plans for unexpected challenges. Collaborate closely with vendors and IT teams, and ensure data backups are in place. Conduct thorough post-migration testing and gather feedback for continuous improvement.

We first need to understand the answers to three questions: 1)Why? This is the first question we must answer because all teammates should follow the same goal. When you have a team that understands the reason for what they do, you can accomplish anything with such an amazing team. 2) How? This starts with requirements. When we know the requirements, stakeholders can generate a plan with appropriate phases and direct zones of responsibility. All the rest is just a step-by-step plan. Also, that there can be some unexpected situations, and there should be a responsible person who controls the process and can make appropriate decisions in critical moments. 3) When? Clear deadlines and agreements with all stakeholders are a must.

Lo esencial en toda migración independiente de la escala es la documentación, se puede tener el mejor equipamiento y los expertos. Pero sin documentación y sin un plan adecuado el proceso puede ser un desastre. Es conveniente hacer una planificación por fases, un route map real y holgado, con pasos establecidos de tal manera que no haya cabos sueltos.

Success comes from planning and controlling your environment. Tests and disaster recovery (DR) should be performed to ensure absolute control even in adverse situations. Remember to have a detailed change plan containing all procedures for each team involved. Backups, operating systems, applications, and databases should have coordinated execution for total success assurance.

Develop a detailed deployment plan, including timelines, roles and responsibilities, and rollback procedures in case of any issues. Provide training and support for staff members who will be affected by the migration, and communicate the changes effectively to all stakeholders.

Desenvolva um plano de projeto que detalhe cada etapa da migra??o, incluindo cronogramas, recursos necessários e responsabilidades. Em um projeto de integra??o do Estado do Tocantins ao sistema CODIS do FBI no Azure, por exemplo, o planejamento detalhado foi fundamental para o sucesso na migra??o.

Do a project plan which includes the following. Inventory all that needs to migrate. Check if migration tools are available. Do a test run on test server. Check backup's Check time lines.

Tests should not be run on separate environments only. Volunteers/test machines in the production environment have to be tested as well in the most comprehensive form possible. Too many times small nuances created different results between different environments. The sandbox test shall be used to get as close as possible to the final results. Production -environment tests will help refine and align to the real world.

Dans un parc non homogène, il faudra veiller à faire le test sur chaque famille et mesurer les résultats pour anticiper toute anomalie.

Prepare for a large-scale operating system migration by conducting a thorough inventory of your environment, including hardware, software, and dependencies. Test compatibility and performance of applications and systems with the new operating system. Identify any potential conflicts or challenges and develop mitigation strategies. This proactive approach ensures a smooth migration process and minimizes disruptions to operations.

Identify some power users. And see what settings, favorite, profiles, configurations for applications and OS can be brought over. What will need to be added and how to do that. This might be a good time to work on naming convention for Printers, locations and leverage a tool to deploy those.

Prioritizing data backup and security is essential in preparing for a large-scale operating system migration. This step ensures critical data is protected and can be swiftly recovered if issues arise during the migration process, enabling a smooth transition to the new operating system.

Backing up and securing data is paramount before a large-scale operating system migration. Organizations must create comprehensive backups of all critical data, ensuring redundancy and minimizing the risk of data loss during the transition. This includes not only user files and databases but also system configurations and settings. security measures should be implemented to safeguard sensitive information throughout the migration process. Encryption, access controls, and monitoring mechanisms help protect data integrity and confidentiality during transfer and storage. By prioritizing data backup and security, organizations can mitigate potential risks and ensure a smooth migration without compromising the integrity or privacy of their data.

S'assurer du bon déroulement des backups systèmes et voir même faire des tests de restauration sur un échantillon. S'assurer aussi que les données utilisateurs et métiers sont également sauvegardées

Data Assessment: Identify all critical data repositories, including databases, file servers, and user devices. Classify data based on sensitivity and importance to prioritize backup and security measures. Data Migration Plan: Develop a comprehensive plan for transferring data to the new operating system. Ensure compatibility between backup formats and the new system. Test data migration procedures in a controlled environment to minimize disruptions. Contingency Planning: Develop contingency plans and procedures to address unforeseen issues during the migration process. Establish protocols for restoring data from backups in the event of data loss or corruption.

In my experience, preparing for a large-scale operating system migration requires a comprehensive approach to data backup and security. It's crucial to have a robust backup strategy in place, encompassing critical data to ensure a smooth restoration process in the event of any unforeseen issues. Additionally, implementing encryption, strong passwords, and firewalls adds an extra layer of protection to safeguard sensitive information during the migration. Informing users about the process and guiding them on securing their own data is also key to a successful transition.

Anyone mentioned 6R's of migration? Are those helpful regardless of what we achieve with scrums, meetings, plans, assess, testing, backups, recovery mode etc.

To prepare for a large-scale OS migration: assess current infrastructure, create a detailed plan, set up a test environment, ensure robust backup and recovery, test application compatibility, communicate with users, conduct a pilot migration, migrate data securely, have a rollback plan, test post-migration, and document the process thoroughly.

How the end users perceive the new system has an effect on migration success. System acceptance is directly related to how users view its usability and is associated with the Technology Acceptance Model (TAM). TAM is determined by two factors, “perceived ease of use”, and “perceived usefulness”. Both these factors can be greatly improved through well executed user communication and user training. Increasingly organizations are bringing in end users at the beginning of a major migration project, e.g., the use of agile methodologies in which the user is engaged upfront as part of defining the user story, as well as during acceptance testing. This provides hands on experience to the user and I improve chances of a flawless system acceptance.

Any change that will affect what a user sees on a daily basis requires a well built change management plan. The user has developed muscle memory for the tasks they do currently, which requires the change to be managed in a way that meets the needs of the project and the needs of the user. The users (or their champion) need to be involved in the planning and development of any training materials that are created and used for the change. Having the end users identify the common functions or clicks within the OS will help create a tailored training experience that will resonate with the end user, helping to increase the acceptance of the change, leading to the users being more open to the changes introduced during trainings.

Training user to understand their needs and issues will aid you plan and know what to do and also to assure them. Have a team of technical and customer experience guys to assist with issues and gather information which will help in subsequent deployment or next batch.

Have Pareto analysis of your implementation and ensure the 20 % of most critical processes taken care more then 80 % of routine processes. team should have PDCA to check migration on correct path. have Six Sigma process in each set of migration and control your process with best practices.

My point of view, the post-migration monitoring and evaluation are vital steps. Collecting and analyzing data on performance, security, usability, and user satisfaction help ensure the new operating system meets expectations. Soliciting feedback from users and stakeholders provides valuable insights into any issues or areas needing improvement. Documenting the migration process and results is crucial for future reference and sharing best practices and lessons learned contributes to knowledge-sharing within the organization, fostering continuous improvement.

Considering OS change I would think about how we are going to automate all OS administrative burdens like performance management, high availability and disaster recovery, etc. automated adjustments toward smart infrastructure and eventually evolve to infrastructure as a code.

Document the entire migration process, including lessons learned and best practices, for future reference and improvement. Evaluate the success of the migration against the predefined objectives and gather feedback from users to identify areas for further improvement.

Compatibility Check: Assess app and hardware compatibility. User Training: Prepare end-users with training and support. Clear Communication: Maintain transparent communication. Thorough Testing: Validate OS and migration process. Contingency Plan: Plan for rollbacks if needed. Documentation & Training: Document and train for smooth adoption.
