Replace multiple drives on PS5000e

I'm getting 3 replacement drives from Dell to replace healthy drives whose firmware can't be updated (the 3 current drives are all replacements for failed disks we've had in the last few years). I expect the new drives today, but I forgot to ask the storage tech the proper procedure when I was on the phone with him yesterday. One of the current drives is the spare and the other 2 are hot. I'm guessing that I:

- replace the spare first and check the EQ - I don't expect any rebuild time, but is there anything else that might take some time?

- replace the first hot one and wait for full rebuild, which should finish over the weekend

- replace the second hot one

Am I missing anything?

Thanks.
