Sizing and upgrades

#Goal

Pick CPU/RAM/disk for your class size and plan upgrades.

#Sizing tiers

Prefer bare-metal USB for deep nested QEMU.

#Recipe: before a big class

1. Confirm Launch Budget / free disk on Home
2. Pre-import images
3. Cap student quotas
4. Smoke-test one Certified platform end-to-end

#Upgrades

#In-place update package (preferred for API/UI fixes)

See In-place updates. Example:

sudo vexnx-update apply /path/vex-nx-1.0.44-to-1.0.45-amd64.vxp

#Full OVA / USB (major releases or OS changes)

1. Export / note management IP and licence file
2. Deploy new OVA or re-flash USB ISO per vendor instructions
3. Re-import images if the data disk was not preserved
4. Re-activate licence
5. Confirm Compatibility Certified chips and Docker seeds

Always read the release notes for the version you install (example artifacts: vex-nx-1.0.44.ova).
