Recommended approach on replacing SSD

[Airw0lf]

Hi Team,

I have a basic Proxmox install with a single, 2-TB SATA-SSD. For performance reasons I would like to replace this with a 2-TB NVME-SSD. The current partitions are shown in the list below.

The idea was to use CloneZilla for this transition. That approach fails because as seen in the list below, the NVME-SSD is smaller then the SATA-SSD (about 100 GBytes).

To overcome this problem I booted the system with a USB-drive (Linux Mint) with the idea of decreasing the sda3 partition a bit.

However, I'm not sure if (and to what extend) this ruins the Proxmox install because gparted reports this partition as secured. In addition it looks like this sda3 contains several other partitions - one of which is pve-data of 1.7-TB.

Any suggestions?
And more in general: what is the recommended approach for making this happen?


With warm regards - Will

very difficult: if u have low affinity to it then buy a bigger nvme otherwise look here:
