Networking Considerations

VMware Aria Automation 8 includes these NSX, Load Balancer, and Security Group considerations.

NSX (T/V) Considerations

Nota: These considerations only apply to vSphere Networking with NSX.

The VMware Aria Automation 8 Migration Assistant does not support blueprints with a private network component that do not contain a private network profile for migration.

In VMware Aria Automation 8, every on-demand NSX-T network creates a new Tier-1 logical router, and every on-demand NSX-V network creates a new Edge.

When migrating NSX components from VMware Aria Automation 7 to VMware Aria Automation 8, they are renamed.

Tabla 1. Blueprint Components

vRealize Automation 7 Component	VMware Aria Automation 8 Component
NSX-(V/T) On-Demand Nat Network	Cloud.NSX.Network (networkType: outbound) + Cloud.NSX.Gateway (Only if Nat rules specified in 7 BP)
NSX-(V/T) On-Demand Routed Network	Cloud.NSX.Network (networkType: routed)
NSX-(V/T) On-Demand LB	Cloud.NSX.LoadBalancer
NSX-V On-Demand Private Network	Cloud.NSX.Network (networkType: private)
NSX-(V/T) Existing Security Group	Cloud.SecurityGroup
Existing Network	Cloud.vSphere.Network
NSX-V On-Demand Security Group NSX-V Existing Security Tag	Not Supported.

Tabla 2. Deployment Components

vRealize Automation 7 Component	VMware Aria Automation 8 Component
NSX-(V/T) On-Demand Nat Network	Network Component (networkType: outbound)
NSX-(V/T) On-Demand Routed Network	Network Component (networkType: routed)
NSX-(V/T) On-Demand LB	Cloud.NSX.LoadBalancer
NSX-V On-Demand Private Network	Network Component (networkType: private)
NSX-(V/T) Security Group	SecurityGroup Component (type : Existing)
Existing Network	Network Component (networkType: existing)

Tabla 3. Endpoint Mapping

vRealize Automation 7 Endpoint	VMware Aria Automation 8 Endpoint
NSX-V	NSX-V Nota: The NSX-V endpoint is linked to vCenter.
NSX-T	NSX-T Nota: The NSX-T endpoint is linked to vCenter (1:N Mappings).
NSX-T and NSX-V	vCenter (Hybrid) Nota: All 3 endpoints are migrated but only the NSX-T endpoint is linked with VC. If needed, you must manually create additional links.

Network Profiles

If your vRealize Automation 7 source environment contains both reservations and a network profile, they are merged during migration into one Network Profile in VMware Aria Automation 8.

Tabla 4. Network Profile Conversion

Name	vRealize Automation 7	VMware Aria Automation 8
External Profile	Assigned to Network in the Reservation	Equivalent CIDR is set on the 8.x subnet. Ip Ranges are set on the subnet.
Routed Profile	Linked to External Profile. External Profile is set on the DLR or Tier -0 Logical Router in Reservation.	A Separate Network Profile with Isolation Type as Subnet is created. The equivalent CIDR (of VMware Aria Automation 7 routed profile) and subnet is determined and set in the NP. Subnet size is determined by the VMware Aria Automation 7 subnet mask.
Nat Profile	Linked to External Profile. External Profile is set on the DLR or Tier -0 Logical Router in Reservation.	A Separate Network Profile with Isolation Type as Subnet is created. The equivalent CIDR (of 7 VMware Aria Automation nat profile) and subnet is determined and set in the NP. By default, the subnet size is 29. If VMware Aria Automation 7 has both DHCP enabled and static IP ranges, VMware Aria Automation 8 assigns DHCP and Static as the IP range.
Private Profile	Linked to External Profile. External Profile is set on the DLR or Tier -0 Logical Router in Reservation.	A Separate Network Profile with Isolation Type as Subnet is created. The equivalent CIDR (of 7 VMware Aria Automation private profile) and subnet is determined and set in the NP. By default, the subnet size is 29.

Nota: External IPAM is supported for all network profiles. However, the CIDR is not set and the IP blocks of the IPAM are set as ranges.

When creating Network Profiles, you must select the address space and existing IP blocks.

NAT Network Profile with Third-Party IPAM

In vRealize Automation 7, you didn't need to select the address space. Only the IP ranges were specified in the Network Profile. During deployment, a new on-demand address space was created and IP range set.

In VMware Aria Automation 8, when creating a Network Profile you must select the address space and existing IP blocks.

Security Groups

In VMware Aria Automation 8, Security Groups are linked only if you have a Network component. During Blueprint/Deployment migration, a network component is created by default when a VM is not attached to a Network Component.

For vRealize Automation 7 blueprints, the static IP is assigned to the NIC without having to link a network component. During migration to VMware Aria Automation 8, a default network component is created for these blueprints.

Azure Networking

VMware Aria Automation 8 supports Azure blueprints with these components:

• With Security Groups.
• With vNET and Subnet

Nota: VMware Aria Automation 8 does not support Azure blueprints with load balancers. You must create a new load balancer.
