[SOLVED] Advice on how to replace data drive?

Hi,
I'm planning to replace my data drive by another one, bigger. Both are SSDs. There is no raid, and only one single partition on the source drive.
I think I should copy the data with dd and then extend the partition on the new drive, but then how to proceed with OMV? Should I go the hard way and modify config.xml (while both drives are present) and reboot the nas once config.xml has been modified?

Am I on the right way? Would you have advice on how to proceed? Thank you!

Oh my... Why do simple things when one can do complex ones? Thank you for the obvious answer, I wonder why I wrote the post above...

RomainD2, that tuto seems to be for an old version - v4.x backup plugin does not even need a restart, it's a live backup.
You could still use Clonezilla manually for this if you want (Clonezilla gets installed in the OMV-Extras menu)
