Artigo desenha as melhores práticas. Tem que se fazer teste antes de implantar, deve-se ter um plano de volta ( rollback plan ), comunicação fluída e clara com todos os envolvidos. Mas a decisão de volta, requer um cuidado e, dependendo da situação, uma decisão colegiada. O que está em pauta; tem como resolver com mais tempo; quais riscos em não atualizar e seguir com a volta; tem tempo para fazer nova tentativa com os experts? Também há situações que não permitem a volta, isso tem que ser visto antes da execução, avaliando se todos que podem resolver estão envolvidos e disponíveis para ações de solução ou contorno.

To prevent major disruptions during system upgrades, follow these steps: 1. **Plan and Test**: Create a rollback plan, test the upgrade in a staging environment, and check dependencies. 2. **Communicate**: Inform stakeholders and schedule upgrades during off-peak hours. 3. **Monitor**: Use real-time monitoring and alerts to track the system's health. 4. **Incremental Upgrades**: Upgrade in phases to minimize risks. 5. **Backups**: Ensure full backups are taken and verified. 6. **Automated Testing**: Run automated tests before and after the upgrade. 7. **Documentation**: Document the upgrade process and changes made. 8. **Team Readiness**: Ensure your team is ready to handle issues quickly.

Following tips can decrease risk of upgrading interruption: - Having tested and written document of upgrade plan including upgrade phases and description of different scenarios and cross checking codes, commands and queries - Having written and tested document of roll-back plan including scenarios of back up and restore in addition to estimated time to roll-back in each phase of the project.

Upgrading IT operations is an essential part of keeping up with technological advancements. However, it can often lead to challenges and disruptions if not handled properly. Effective communication techniques play a vital role in ensuring that IT operations remain smooth during upgrades.

Everyone answered what to do to prevent, but the real gravy here is what to do WHEN it occurs.Here's how I approach it: When challenges arise, it’s about activating contingency plans, engaging the right technical teams, and maintaining open lines of communication with everyone involved. After every upgrade, I analyze what went wrong (and right), document key takeaways, and refine processes for the future. At the end of the day, preparation and transparency are your best tools to navigate these situations effectively. Cheers 🤘
