Changing careers at 8 years into a job, is it realistic? after 8 years as an IT help-desk technician

After 8 years as an IT help-desk technician I am thinking about moving into a different field. This is my first time dealing with any of this. I have a little time and a small budget for training. Has anyone made a similar move?

I began with informational chats, then a short online course, then a related entry-level role. It took about 12 months.

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
