Domicile for CA FTB when keeping home in 2 states

Hi,

I am moving from CA to TX.  I have a home in CA that I'd like to keep (not rent out or sell), say, as my vacation home. I will be buying a home in TX (which will now be my primary residence). Will keeping the home in CA create a problem wrt CA tax audit? Please assume that I will be doing the following

  1. Updating DL to TX
  2. Registering cars in TX
  3. Updating addresses on bank accounts (do I need to close old bank accounts like

  4. Updating addresses on credit cards, insurance policies,
  5. Updating address in my employer's records (employer will adjust the tax withholding after the move)
  6. Registering to vote in TX
