How to HA Grid migration from Appliance to vNIOS?

We are going to migrate our existing environment with new virtual ones.

Currently our grid exists of the following:

Old:

Master 2x IB-1410 (physical) (HA)

Member 2x IB-1410 (physical) (HA)

 

New:

Master 2x IB-VM-1415 (HA)

Member 2x IB-VM-1415 (HA)

 

New and old are all running software version: 8.3.6-385000

Requirement: all VIP IP's, hostnames and data should be maintained.

 

Replacing the master should not be a big problem i think:

- add HA pair to the grid

- make it candidate master

- let it sync DB

- promote it to master using cli.

- Remove old master from grid

- adjust hostnames and VIP IP

and we are done

 

But how do I accomplish the same with members?

I cannot make it candidate master since it will not be master at the end so what is the best approach to migrate and keep all data?

 

The new VM's are already in HA mode but not sure if that was a wise decision?

Hi Richard,

 

You are correct. The steps you had mentioned for swapping the grid master should work.

 

To swap the existing HA pair, first you can perform a database reset on the passive node of HA member using the command "reset database" from CLI. Now join one of the new appliance to the existing grid as a passive node.

 

After syncing it with the existing grid, perform a failover so that the newly swapped passive node becomes the active node.

 

Once completed, you can perform a database reset on the new passive node which is an old appliance and replace it with the new appliance.

 

I hope it helps.

 

 

Thanks,

Alten Alexander

Hi Alten,

 

Thanks for your explanantion but i thought you cannot replace hardware with virtual in HA (or vice-versa) in a cluster? Member type vNIOS versus Infoblox conflict plus 1410 vs 1415 ?

 

Let's say you can. With a bit more detail the steps would be like this then:

 

- login to PASSIVE node

- reset database from CLI

- swap PASSIVE node in HA config with NEW node (all devices are in the same subnet)

- sync database

- force failover so newly added node will be ACTIVE

- repeat above steps for current PASSIVE node

 

Did i understand it correclty?
