Hi, we curently have a VM window server running a SQL Database, the disk format is qcow2. And we want to change from qcow2 to raw to increase it performance.
I have check the document but it have no example of qcow2 to raw https://pve.proxmox.com/wiki/Storage_Migration

What should we consider, be cautious when changing disk type ? Is there any best practice when do it ?
Should it cause any downtime when we change the disk type ? Does that affect the db (the sql db always run query)
