Transferring Investments from TDIF to Index Funds

Hello,

I have a question about transferring investments in my Retirement Account.

I have some money invested in Target Date Index Funds, under my Traditional and Roth IRA due to rollovers from my old jobs. I kept investing in my Roth IRA only for the TDIF, but after learning more about the pros and cons of them, I rather invest in Index Funds (e.g. FZROX). I have a few questions about this:

  1. Am I able to somehow transfer or sell my TDIF stocks to acquire or purchase index funds I’d like to invest in? And if so, what would be the consequence if I do?
  2. Is it smart to leave the funds there and just start a new investment in my Roth IRA going forward?

Thanks for any assistance with this.
