Migration to Openstack from Proxmox

We currently are using proxmox for a envrionment management, and while we were looking at DFS options we came across openstack, and we've decided to start looking at it as a replacement for proxmox. Has anyone made this migration before? Currently we're running a few Windows Server 12/16/19 virtual machines, but mostly centOS7 virtual machines, however what we are developing are micro-services that ideally would be deployed using k8s. Does anyone have any experience migrating between the two, or any other recommendation when considering openstack?
