[Users] Migration after kernel upgrade

[Alexander Prinsier]

Hello,

I'm wondering about the kernel version requirements when migrating a
container from one HN to another HN.

Suppose I have 2 HN's with the exact same kernel. I have one container,
running on one of these HN's which I don't want to bring down. Some time
later a kernel update comes out. I upgrade the HN which is idle.

Will it be possible to migrate the container online to the idle HN after
the kernel upgrade?

If not, how am I supposed to prevent downtime to this container without
missing critical kernel upgrades?

Thanks for helping!

Alexander
