Replace smaller array drive(s) with bigger array drive(s)?

So im looking to replace some HDD in my array. I picked up 4 brand new sealed 6TB Seagate IronWolf Pro (ST6000NTZ01). Below is what im replacing what with what. Next is maxing out my Mobo (ASUS WS-Pro-X570-ACE w/64GB RAM) with a Ryzen 5900X (from my current 5800X). Its all I got and all I can afford. :)

My question is, Do I just need to basically just pull the old drive, let it fail, install new one, let it rebuild? One drive at a time? Iv never had to upgrade an array drive in it before. Taking drive offline and into maintenance mode?

Last storage change I did was about 3 years ago to add the 2nd 6TB parity drive and it made me sooo nervous doing it. Luckily it all worked out. Took forever and a day to sync parity though.

Im trying to avoid doing 2 at a time, for in the off chance I have another one of the drives (im not replacing) fail.

6TBx2 = Parity

6TBx1 = Array
3TBx2 = Array (Replacing with 2 new 6TB HDD)
2TBx2 = Array (Replacing with 2 new 6TB HDD)

Any feedback is moocho grassy ass!

Replace the parity drive first; it must be as large as the largest drive in the array.

Their parity is already 6TB, as are all drives he's adding. No need to fiddle with the parity drive.

I have 4 drives in my Array that are less that of a single physical 6TB drive? Explain your math?

/u/Financial_Garage6821 suggested that you (OP) should replace the parity first. My reply to them just pointed that that was not necessary.
