Hi All,
I have found that currently vMotion is stated in the config guide as being supported. Is that correct? In a previous post that was closed I could read that this was not supported yet.
If it is supported, what are the limitations and guidelines?
Thanks in advance!

vMotion is listed as supported but we have received reports of issues with current ISE versions. ISE does not have a facility to stop/pause the db operations during vMotion and so this may lead to data corruption issues. A similar issue exists with snapshots.
We have a request in to QA to validate the current caveats / restrictions and update documentation with current status. In short, I would not recommend vMotion at this time. However, you should be able to shutdown and replicate/migrate VM without issues.

@Craig Hyps any new information on vMotion recommendation with ISE2.4/2.5?

Hey!
Thank you very much for the answer. We heard of this, but when we saw it in the guide we thought that this might have changed. I will pass on the information and I look forward to the support of vMotion in the future.
Thanks again!

Looks like we just hit this bug as well.. MNT node vmotioned and now certain UI elements aren't loading. TAC case opened.. Have disabled automated vmotion for now.

Is there any road map to implement a permanent fix? Having these as VMs is really harming our ability to have a fully hands off and automated patching or upgrade cycles. This seems ridiculous for a multi-billion dollar software company...

If you are a Cisco employee you can use the internal page http://cs.co/ise-pm to discuss with the product managers. If you are a customer or a partner then you can use http://cs.co/ise-feedback to remind them of the enhancement request.
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvn60474
They won't discuss road maps for products on the public communities.

Is Cisco ever going to fix this? If so, when can we expect it to be fixed? Been a problem for years now.

Hi @todd.roberts11 ,
ISE SNS 3600-Series only support cold vMotion (please take a look at: ISE 3.0 - SNS 3500/3600 Series Appliances and Virtual Machine Requirements).
Note: you can open a TAC Case and ask TAC to add your case to the CSCvn60474 - Ability to perform vMotion while ISE VM is up and running .
Hope this helps !!!

I've read the documentation, Marcelo. What Im asking is if you ever plan on fixing the problem?

The bug filed is a feature enhancement. ISE uses an in-memory distributed database which that does not react well to the quiesce of the disk that occurs as part of the hot vMotion operation.
As stated earlier in this thread, roadmap is not discussed on this public forum. Please use the feedback mechanisms provided at http://cs.co/ise-feedback or contact your Cisco account team so they can request any updates from the ISE Product Managers.

Greg, most of us have been living with the problem for years now and have a sound technical understanding of the applications fragility. I don't see anyone on here asking for another technical write up on why it doesn't work, do you? We aren't asking you for trade secrets, we just want to know if you have the slightest intention of ever fixing an obvious and debilitating flaw with your product. Sounds a lot like no. What is the benefit of virtualizing this application if it can't use the the most critical features of the hypervisor?
