Darwin was right!
It's not the most intellectual of the species that survives; it is not the strongest that survives; but the species that survives is the one that is best able to adapt and adjust to the changing environment in which it finds itself.
The IT sector, like the medical profession, is one of those rare careers where adaptability is crucial to the success of one's career; and where lifelong learning is taken for granted. The moment you stop learning, and allow your skills to stagnate, the market will have moved on without you; and you, and your career, are pretty much dead. We have seen this many times over the years, be that companies that are still stuck with Windows 2003 Server, or still developing applications in VB6; whilst everybody else has been espousing the joys of virtualisation, and developing on the latest .Net platform for many years.
What is important is that whatever aspect of the IT sector you are involved with, be that development, support, networking etc, ensure you keep up with all the developments in your technology; and do not allow your skills to stagnate. Read magazines/blogs, follow communities online, get involved in beta testing of products. In essense keep abreast of everything that is happening with your technology, and how it will evolve in the future. By having an eye on the future, you can at least have an appreciation for the ramifications of your technology in the future, and therefore plan for it.
If your employer is unwilling, for whatever reason, to upgrade to the latest (or newer versions at the very least!) , it may well be a good idea to look for a new job. This is particularly true when there has been a shift in the use(and demand) of, for example, a development language, or the end of life of a software/OS/Server (eg Windows Server 2003).
