I'm planning to migrate a Cisco 9800-CL Wireless LAN Controller HA SSO pair from VMware ESXi to Proxmox and would love to hear from anyone who has experience with this process. I'm trying to figure out if it's possible to move my existing VMs directly or if it's generally better to set up new 9800-CL VMs on Proxmox and rebuild the HA pair from scratch. I'm also looking for tips on any challenges or limitations related to using 9800-CL on Proxmox, particularly concerning HA SSO, interfaces, or performance. It would help to get some high-level advice on the best approach, the order in which to do things, or any lessons learned that could make this smoother. Since this is a production WLC environment, stability and supportability are key for me. I'm more interested in real-world experiences than specific command lines. Thanks in advance for any insights!

It might be a lot cleaner to just back up your config and set up fresh VMs on Proxmox. If you end up needing to rebuild anyway, this plan can save headaches down the line. Plus, moving the VMDK files directly into Proxmox should work, but make sure you convert them to the QCOW2 format first.
I don’t have direct experience with the setup, but I found a helpful blog post that details the process: [How to Set Up a Cisco 9800-CL Wireless Controller on Proxmox Without Losing Your Mind](https://www.adjacentnode.com/post/how-to-set-up-a-cisco-9800-cl-wireless-controller-on-proxmox-without-losing-your-mind?_bhlid=2587e32cd21c1e6e6d5cdb736c12c36369bd729e). It might have some useful insights for you!
Honestly, I see a lot of people trying to migrate directly. It seems like the best approach is to start fresh on Proxmox, especially for production environments. Always better to have a clean slate rather than deal with unknown issues after migration. Stability should be your top concern, and rebuilding gives you that control.
Agreed! There's less risk when you build fresh. Plus, you get to configure everything to your needs from the start!
Definitely do the conversion! It makes the migration process smoother.
