This question already has an answer here:

I'd like to move my accounts from the eth client to geth. Also, I'd like to keep the same addresses. Is this possible?

This question was merged with Convert an eth key to a geth key because it is an exact duplicate of that question.

  • This is an exact duplicate and you even include the original in your answer. Why creating a new thread? I'm tempted to merge your answer to the other question. – Waqar Lim Mar 23 '16 at 9:51
