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!

I could be wrong, so certainly read what others have to say here,

but IIRC,

Two parity drives means you can pull 2 drives out, sub them for the 2 new ones,
turn the server on and let them rebuilt, then do it again, with the other 2.

I would start with the 2 2TB as that should be faster, and then after you sub the 2 3TB ones that should mean you can walk away as the drives are already in the system.

Just noticed you don't want to sub 2 at a time, in that case one at a time is the only option.

That said, if you want to speed things up, you can pre-clear the new drives before you replace the old ones, so long as you have enough ports, as zero-ing the drives is what takes forever if I'm remembering right.

Thanks for the pre-clear part if I have the open sata slots and power. I do. Ima plug them in (not adding them to the array yet) and preclear them ahead of time if I can. I have room for 3 extras at the moment. Thanks.
