Upgrading storage on server

[Laynord]

Hi so .
A friend of mine is planning to upgrade one of his server's drive from spinning rust to ssd's 
only issue his current setup is a raid 5 array and I have read that you cannot switch drives / rebuild missing one on ssd's ( or if it does will limit speed to HDD and do weird stuff ) 

What process do you advise to copy current raid array from one set of drives to another .
I am currently thinking of using another computer to copy drive data from one to another one by one from the raid array ones to the new ones ( keeping order and stuff ) 
Is it even doable or am I missing something in either way to make it easier or undoable
Current drives are SAS 900G
future are planned to be micron 1100 ssd's 1to
server is a dell R630 wich suppositly supports Sata and Sas

Do you have empty drive bays?

 

I have seen those dell perc cards in  the past don't support mixing hdd and ssds in a array, so you can't jusr swap the drives one by one in the raid array.

 

Can you get a bigger ssd? Id get something like 2x4tb ssds in raid 1 then you use less drive bays in the server, and can use both arrays at once.

Id do that dd method for the drives then. Order won't matter, so just clone all the drives over.

 

Make sure you have backups. I'd probably just make a new array and restore backups.
