Upgrade from 6.4 to 7.4

[ChFin]

Hi all,

we have a Proxmox HCI Cluster (proxmox-ve 6.4-1, kernel 5.4.114-1-pve) and Ceph 15.2.11. We would like to upgrade to version 7.4.
Can we go in one step from 6.4 to 7.4 with Ceph 15.2.11 and then upgrade Ceph from octopus to pacific ?
Are there any issues to be expected since Ceph Octopus is not supported starting from PVE 7.3?

Thank you
