Absolutely doesn't work that way. If this is a Soft raid then You can put larger drives in 1 at a time and you will have to do this TWICE. Then rebuild the raid going from critcal back to normal. Then you can extend the partition to the free space. If its a hardware raid you are going to have to create a new container on blank drives and clone via bootable dvd or USB to and from a USB drive that can hold all the data.     
I have T110 server with raid 1 and need to put larger drives in.  Do I need acronis or with raid one can I just leap frog disks.  Can I put in larger disk in second drive bay let disk 0 copy ot new larger disk and then swap disk 1 into disk 0 and put another new disk in 2nd  bay.
