A team member of yours, suggests to replace the current CI/CD platform used by the organization with a new one. How would you reply?

Things to think about:

• What we gain from doing so? Are there new features in the new platform? Does the new platform deals with some of the limitations presented in the current platform?
• What this suggestion is based on? In other words, did he/she tried out the new platform? Was there extensive technical research?
• What does the switch from one platform to another will require from the organization? For example, training users who use the platform? How much time the team has to invest in such move?
