I'm a software developer, but I don't like my job now. Suddenly I have a urge to switch my role to analyst in some VC fund or maybe in corporate itself, is it a good idea. And how can I do so.

Bhai ye urge-verge kya laga rakha hai. Seedha bol zyada pese chahiye.

The best thing is you have time. Understand what's the expectations from the roles that you are interested in. If you feel confident enough then start searching for entry level roles on LinkedIn and apply. (Also do some basic online courses for signalling)
