Good afternoon,
We're in the early stages of decommissioning / merging 2 (small) datacenters into 1. We'd like to decommission 1 of the CP HA clusters and move all networks/rules/NAT/VLAN, etc onto the remaining CP HA cluster.
Has anyone done anything like this or have any advice they'd like to offer?
Items we have already considered:
-Turn down VLANs/networks on to-be-decommissioned cluster, bring up on other. (In GAIA)
-Document topology of to-be-decommissioned cluster to apply it to remaining cluster in next step.
-Pull/Update topology on remaining cluster (SmartDashboard)
-Ensure VLANs are built into switching infrastructure to handle both datacenter VLANs
-Modify NATs to install on the remaining cluster vs the cluster that is going away.
-Move static routes to remaining cluster
Is there a way to script the turn-up of new interfaces/VLANs on the remaining cluster to minimize downtime of the datacenter equipment that is having its cluster decommissioned?
Sure thing: simply write the Gaia configuration changes in the text file and paste it into your target cluster's members.
Once executed and "save config", you'll have to perform "Get Interfaces" in the cluster's properties and manually configure vIPs and topology of the newly imported interfaces.
The objects and rules could be pre-configured and rules disabled in advance.
Once cluster configuration is changed, enable the rules and push the policy.
You may consider cloning the policy package before introducing the changes for the fallback capability.
