I created tradition IRA for 2013 and filed my tax returns. Now, i think, i made a mistake by not opting for ROTH IRA. I have some shares with some unrealized gains. Is there any way to convert traditional IRA to Roth IRA without liquidating my positions and paying taxes on gain? I am fully aware of the fact that i have to pay taxes on the contribution amount.

Is it possible to just amend the tax return and change the a/c type since i opened those just few months back.
