It really depends on the situation.
If The New Manager is intent on making their fast-track bones by shaking things up, the entire tech level may soon be outsourced.
What is important is what you want.
Do you want to give management a try?
Do you want to learn The New Manager's style of managing?
Have you ever thought 'if I were running things we would not be doing X, we would do Y'?
I suggest you give it a shot, maybe you will like it.
If you turn it down, be sure to give The New Manager every reason to know that you are just too darn essential in the tech role to be moved out of it.
Either way: Get your resume out there, and start actively looking for a new job.
Good Luck!
