Switch from development to Support

Surya,

It depends what will be your responsibilities in new role, if you will still be hands-on then there are no issues to have new job one after another. Else, you might find it challenging.

Its hard to say until you join what an organization will put you into. so do your research and proactively analyze the situation before you accept this new role.

Its advisable to speak to manager of the team (HR Can arrange a phone call) and you can understand what team actually do and what will be your day-to-day responsibilities.

Good Luck.
