Sorry to insist... but even for btrfs RAID1 disks of différent size ?
OK, I shall try but I am surprised it is so simple... ;)

Yes, should be so by default.
Good luck!

Thank you. I am surprised; update-grub is enough to install grub
correctly on all drives...??

My way:
- Boot with a live cd with clonezilla on it (i.e. clonezilla live)
- clone the complete harddrive to the new one. Pay attentention, that
the new one must be equal or bigger than the source.
- Use another live cd with gparted on it and move or resize the
partitions.
------------------------------------------------------------------------
Second way (more work and more complicated):
- Boot with a linux live system (debian live, Knoppix whatever)
- mount the old one to a new mountpoint in root, like /disk1
- partition the new drive to your needs manually
- mount the new one to a new mountpoint in root, like /disk2
- use rsync for transferring data to the new one
- reboot to your old system with the connected new harddrive
- install grub on the new harddrive (grub --install /dev/sdb or
update-grub might do it)

I have a btrfs RAID1 system. I did install it with /dev/sda disk (efs on
sda1, btrfs on sda2). Then, after install, I added a sdb disk (vfat on
sdb1, btrfs on sdb2) and I did btrfs balance.
As /dev/sda is now old, I want to change it. I know btrfs procedures but
I do not know grub procedures.
I suppose I should install "some grub thing" on sdb1 and inform the
system to boot on sdb1. How to do that ?
Is there a good tutorial that I have not found ?
Is it possible to have a system booting automatically on sdb1 if sda1
fails ?
In fact I did add later an identical sdc disk...
