Capital Gains/IRA Distributions in Old State and New Permanent State

My wife and I (both over 65) will have no income from work or Social Security in 2020, but require traditional IRA distributions and perhaps capital gains from stock sales to provide for living expenses for the first few months of 2020. We plan to continue living in Kansas for those first 4-5 months of 2020 and then establish permanent residency in Florida for the remainder of the year.

 

My question is: if we generate a lump sum IRA distribution or sell stock with long term capital gains in January 2020  (to just cover expenses for the first 4-5 months of 2020), will we still owe state taxes in Kansas on that income? Or since we will be established residents in Florida, those IRA distributions, capital gains, and even dividend/interest income for the entire year, will all that income be taxed at the 0% rate in Florida and no tax from Kansas?
