I would start by asking "What is my purpose in seeking to make a switch?"

Knowing your 'why' will help you know for sure if you are able to make the commitment required to make a switch. In general it will take a non-trivial amount of effort to make the change.

If you are confident that you genuinely want to move to the new field then it is all about learning and growing the skills required.

Get 1% better every day in that field and within a reasonable amount of time you'll have the proficiency to at least get entry level position.

Best of luck to anyone on this path!
