Trending @Infosys; Is transitioning from a senior systems engineer to an analyst role a good step?

SSE to TA is an automatic transition if you have fulfilled the criteria like yoe and all. It's a good step and comes with an increase in compensation. Can't guarantee if the work changes but at least there will be a little more money

Yes, it's a smart move. You'll escape routine tasks and dive into analytical work. Just be ready to learn new skills like SQL and Python.
