I plan to PC / downgrade my CSR to another freedom card. Maybe I reapply for another Sapphire card later, we haven't been putting much spend on Chase cards over the ~2 years. I still have an Ink plus card that has a separate login from my personal cards.

I presume I can easily move UR from my personal cards to the business login for partner transfers? Anything that I should consider here? I dont want to lose the ability to taster the UR from my personal accounts.

The biggest loss is downgrading the CSR will be the 3x on travel. Some travel is covered over other cards (e.g., Air, or 2x on other cards), but Chase has a pretty wide definition. One strategy I am considering is either PC'ing my Ink Plus or applying for a new Ink Perferred to replace 3x travel at $95/yr. Obviously I would prefer to get the SUB on a new Ink card (assuming I'd be approved and spend $15k - which is a big spend requirement), but am I crazy to get rid of my old Ink Plus card? I don't see a reason to keep 2 business cards. I don't spend much at office supplies and only use the Ink card for telephone/internet - getting 3x in travel is > than the loss of 2X on phone/internet.
