We noticed today that our oldest Clearpass VM is using a Flexible network adapter. This server was setup before me or my sys admin were employed at our company.
Would it break our server to change this to VMXNET3 adapter type to enable our 10G connection? Apparently this is disered for faster migration, but also I have been informed that this 'flexible' adapter is halting migration of this VM to a newer host.
We foudn this strange because we have a newer clearpass VM that we setup about 2 or 3 weeks ago as a means to expand our licenses. This newer server was setup on e1000 adpater by default. Since this server doesn't service anyone we changed it to the VMXNET3 adapter and haven't noticed an issue.
I guess my question is. What, if anything, will break if we change the adapter type on our current production Clearpass VM to VMXNET3?
A side question being, is there any reason that can be thought of that this server was setup with a flexible adapater?
