Consolidating IRAs or not?

I have mainly two IRA accounts, one is a SEP IRA and the other is a Traditional IRA. The SEP IRA has the majority of funds around 3× as much as the Traditional IRA.

Since it is getting on time to start withdrawing funds I was wondering if I should:

  1. Consolidate the all the funds into the SEP IRA
  2. Withdraw funds equally or proportionally from both
  3. Withdraw funds from the Traditional IRA first
  4. Withdraw funds from the SEP IRA first

 

What would be the pros or cons for any of the choices?

 

Thank in advance
