Real World: OLVM 4.5 Host and Engine upgrade from OL8 -> OL9
Looking for hints, tips and experiences from those on here that have actually gone through the OL8 → OL9 OS upgrade process on both the KVM Hosts and the Engine.
Yes, there are docs out there and we can raise SRs but what with this being a 'community', would love to hear from anyone who as gone through the overall process and describe if it's straightforward and trouble free or if we are going to be going down a road of pain.
Any advice, about going through this process would be appreciated as I've got 7 Separate OLVM Clusters that need to go through this process.
