I cannot make general statements, but it's really hard to move when you are assigned to a project where you unhappy. I tried to transfer to several other teams in my area of expertise. I was quite close in a couple of places, but they usually run out of 'head count' at the last moment. There was just one team that could have taken me, but it was the same kind of boring custom coded BI I was doing in my project. Finally, I just had to give up. The bad part is that I did many 20% projects for these other teams, which hurt my chances for promotion.
