Becker, I hope you take MMM123's advice...
Basically, you can group your choice of response to this situation into
1. Fight the change, either overtly or covertly. This can result in you "keeping book" in hopes that when the axe falls, you will be able to prove some sort of wrongful dismissal...I don't know about you, but after leaving a job, spending the next 6 months or more fighting about the past can be a real downer.
2. Go with the change. Suck it up, Kiss a**, Play the office politics, work the system, etc. This is a soul-draining experience in my view, and takes a great deal of effort above and beyond the work at hand. If you were bent toward this type of thinking you wouldn't have started the discussion in the first place.
3. Do your job with the attitude and the quality of professional that extends beyond whichever organization you are currently working within. The advice in MMM123's response is in line with this type of thinking. Go beyond the confines of the situation and look at the organization as a whole. If there are going to be new initiatives, what questions need to be asked and answered at the beginning, before implementation? How do you ensure that this intiative helps the business meet its stated goals? What stakeholders need to be on board and invested in the outcome? What information does the IT department need to support these intiatives and technologies? Ask these questions in the presence of others than just the new manager present. Remember, this is not "sucking it up", because your intention is not to fit into the organization and its politik, it is to influence the organization positively while you are there. The goal is not to "make nice", but to be respected for your abilities. (The people that respect you can also be good references later on, BTW). This new guy isn't going to be your friend, and I wouldn't encourage you to pretend that he is, however, that doesn't mean he will not respect your abilities, should you have a higher interest in mind.
This approach of "taking the high road" as some call it, or it could be called "career thinking", rather than "job thinking." In this age, jobs will come and go, but those abilities that set you apart from the crowd will be tremendous assets in your career wherever you happen to be. In addition, you will be able to say, "I made the best effort I could at the time for the good of the organization", and then move on when the time comes. You can then apply and refine those same skills of approaching situations from a proactive, objective, broad perspective to another organization, and even outside of strict IT work. Following MMM123's advice, you may chose to develop a New Technology Initiative document, among others, that are part of your arsenal of tools as you go from organization to organization. That's were your work will come in.
New behaviors may also feel strange at first, so you may find yourself falling into the other two types of approaches while you are still at this organization, if those have been your typical responses in the past. Remember, you are building a career, not just trying to keep a job.
Good Luck.
