Multi-Branch Network Overhaul

Multi-Branch Network Overhaul

  • Thirteen geographically dispersed branches, legacy Aruba Central dependencies, and growing pressure for SD-WAN readiness are forcing many IT teams to rethink their WAN and LAN design in one coordinated refresh. Aging appliances, inconsistent access switching, and fragmented management often translate into fragile VPNs, operational blind spots, and rising support costs just as cloud adoption and security expectations accelerate.

    This guide frames a practical blueprint for exiting Aruba Central where required, standardizing branch access, and introducing Meraki MX security appliances and MS switches as a foundation for future SD-WAN. The following sections focus on how to segment 13 sites into the right MX and MS design patterns, plan gateway transitions, and align hardware choices with operational simplicity, security posture, and migration risk tolerance.

Multi‑Site Branch Network Refresh Friction

Aligning 13 branches on a new WAN, LAN, and SD‑WAN‑ready design is constrained by mixed vendors, legacy contracts, costs, and operational risk.

Multi‑Site Branch Network Refresh Friction

  • Staggered Branch Needs vs. Standard Design

    Each site has different WAN, PoE, and capacity needs, but a fragmented design breaks scale, drives SKU sprawl, and inflates lifecycle cost.

  • Aruba Exit and SD‑WAN Timing Risk

    Phasing out existing gateways while preparing for SD‑WAN can create gaps in resilience, policy continuity, and migration rollback options.

  • Cloud Management and Ops Complexity

    Moving to cloud‑managed security and switching across 13 sites can overload IT if licenses, templates, and change controls are not tightly governed.

Aruba Central Exit vs Meraki Branch Refresh

Compare Aruba SD-WAN gateways vs Meraki MX+MS for a 13‑site refresh, simplifying branch WAN/LAN while staying SD‑WAN ready.

Feature Aruba SD-WAN Gateway–Led Path
Meraki MX + MS Branch Refresh (hot)
 Business Impact
Primary role in your 13‑site refresh Focus on replacing/retaining Aruba Central gateways (e.g. ARB:JM799A, JM962A, JZ872A) as SD‑WAN CPE while keeping existing branch switches if possible. Holistic branch refresh built around Meraki MX security appliances (CIS:MX67/68/75/85/105) plus standardized MS access (e.g. CIS:MS130-24P, MS150-24P-4G, MS225-24P, MS390-48P). Clarifies whether you lead with WAN‑edge continuity or a full WAN+LAN modernization aligned to a single cloud‑managed stack.
Cloud management & operations model Keeps you on an Aruba‑centric control plane with mixed‑vendor access switches, creating separate toolsets for WAN vs LAN oversight. Single Meraki dashboard for MX and MS fleets, unified policy templates, and site‑to‑site VPN/SD‑WAN policy from one console. Reduces operational overhead and accelerates day‑2 changes, ideal for lean IT teams managing 13 branches remotely.
SD‑WAN migration readiness Optimized if you standardize on Aruba SD‑WAN, with rich routing and overlay control but more design work when integrating third‑party LAN and firewalls. Native SD‑WAN‑ready on MX (auto‑VPN, failover, traffic shaping) with clean handoff to future dedicated SD‑WAN or private cloud hubs. Gives you a low‑friction path to SD‑WAN while already simplifying branch routing, security, and tunnels across all sites.
Security & segmentation approach Relies on Aruba gateway firewall/segmentation, often paired with separate third‑party stacks and site‑specific rules per branch. MX brings integrated NGFW, content filtering, and site templates; consistent segmentation enforced from WAN edge to MS access ports. Delivers repeatable, compliant security policies across 13 branches without re‑engineering rules per location.
Deployment complexity & migration risk Typically lower change scope on WAN edge but higher integration/compliance testing with existing LAN and legacy firewalls. Phased MX+MS rollouts per branch with templated configs; more equipment change but highly predictable cutovers. Reduces project risk over the full program: once template is validated on 1–2 branches, the other 11 follow a proven pattern.
Cost profile & lifecycle outlook Capex focused on gateways; ongoing effort and tools cost remain split across vendors, limiting economies of scale. Balanced hardware/subscription cost but larger consolidation of tools, training, and support onto the Meraki ecosystem. Tends to yield better 3–5 year TCO for multi‑site environments where simplicity, speed, and fewer platforms matter most.
Best‑fit scenarios Best when you are strategically committed to Aruba SD‑WAN, have stable LAN gear, and mainly need a Central exit plan. Best when you want a once‑off multi‑site WAN+LAN refresh, unified management, and a smooth runway into SD‑WAN services. Helps you choose: keep Aruba as the SD‑WAN anchor, or pivot to a Meraki‑centric branch stack that simplifies everything long‑term.

Часто задаваемые вопросы

How do I choose the right Meraki MX model for each of our 13 branches during the Aruba Central exit?

  • For a 13-branch refresh, start by grouping sites by expected WAN throughput, user count, and SD-WAN roadmap rather than buying the same MX everywhere. As a rule of thumb, MX67-HW/MX68-HW fit small branches or home offices, MX75-HW/MX85-HW cover midsize sites with higher VPN and security load, and MX105-HW is better for regional hubs that may later terminate more SD-WAN tunnels or guest traffic.
  • Also consider PoE and local survivability needs: branches with only simple Internet breakout may stay on smaller MX, while sites that will host local services or higher VPN density should be sized one class up for headroom. Our team can help you map real traffic patterns, prioritize which sites move off Aruba first, and create a mixed MX bill of materials aligned to your migration phases.

Can Meraki MX and MS switches coexist with remaining Aruba gateways during a phased Central exit?

  • Yes. Meraki MX security appliances (such as CIS:MX67-HW, CIS:MX85-HW, CIS:MX105-HW) and MS access switches (for example CIS:MS130-24P-HW, MS225-24P-HW, CIS:MS390-48P-HW) can interoperate at Layer 2/Layer 3 with Aruba SD-WAN Gateways (such as ARB:JM799A, ARB:JZ872A, ARB:R9D72A) using standard VLANs, static routes, and dynamic routing (where supported).
  • In real projects this is often used to run dual edges during the transition: Aruba gateways keep existing overlays, while Meraki MX handles Internet breakout or pilot SD-WAN edges. The key execution reminders are clean IP addressing (per-VLAN), a clear default-gateway strategy per subnet, and avoiding overlapping VPN domains while you cut over.
  • We typically recommend a branch-by-branch migration test plan, including rollback, before you disable Aruba Central-based policies. Our solution engineers can review your design and interoperability assumptions under free CCIE support. Please note: Specific warranty terms and support services may vary by product and region. For accurate details, please refer to the official information. For further inquiries, please contact: router-switch.com.

What are the main deployment risks when standardizing branch access on Meraki MS switches?

  • The most common risks in a multi-site refresh are not hardware-related but operational: inconsistent VLAN plans between old Aruba LANs and new Meraki MS130/MS150/MS225/MS390 stacks, missing PoE power budgeting for IP phones and cameras, and insufficient validation of uplink resilience to the MX or remaining Aruba gateway.
  • To reduce risk, we advise defining a single reference access design (VLAN IDs, QoS markings, voice/Wi-Fi segments) and then cloning it to all MS switches. For mixed environments, confirm LLDP/LLDP-MED behavior for IP phones and check spanning tree priorities when Meraki MS is introduced into an existing Aruba or legacy LAN.
  • In pilot branches, validate that stacking and redundant uplinks behave as intended before rolling out to all 13 sites, and keep at least one spare switch model that matches your standard configuration to accelerate recovery if issues arise.

How do lifecycle, EOL/EOSL, and future SD-WAN plans affect model selection for this refresh?

  • When exiting Aruba Central and planning SD-WAN readiness, lifecycle is as important as raw performance. You should avoid building your new edge on platforms that are close to vendor end-of-sale or end-of-support, especially for sites that are rarely visited after day one.
  • For Meraki MX and MS as well as Aruba SD-WAN Gateways (JM799A, JM962A, JZ872A, JZ878A, R9D72A, JM538A), we recommend checking each candidate SKU in your bill of materials against our EOL / EOSL checker before finalizing the design. This helps ensure your 13-branch refresh will stay within mainstream support windows during your planned SD-WAN rollout horizon (often 5+ years).
  • Where a chosen model is nearer to EoS, we may suggest stepping up one generation or adjusting quantities so spares and replacements are easier to secure over time.

What should we expect for shipping, customs, and lead time on a 13-branch mixed Meraki and Aruba order?

  • For multi-site projects that combine Meraki MX, MS access switches, and Aruba SD-WAN Gateways, lead time can vary by specific SKU, licensing, and regional stock. For in-stock items, and depending on product availability and destination, shipments may be consolidated or split to help you meet phased migration windows across the 13 branches.
  • To plan properly, we recommend locking down your final configuration early, so our team can propose realistic schedules based on current inventory. Details on available logistics options and delivery paths are outlined under shipping methods. For taxes, import duties, and brokerage handling in different countries, refer to our guidance at taxes and customs duties.
  • Because the environment is time-critical, many customers stage equipment in a central location first, validate templates, then ship per-branch kits; we can help you structure ordering so hardware aligns with that deployment pattern.

How are warranty, returns, and post-deployment support handled for this multi-vendor refresh?

  • For a Meraki–Aruba mixed design, hardware warranty is determined by each vendor and product line, while Router-switch.com provides procurement coordination and post-sales escalation assistance. You can review our general policies in the warranty policy section, and see instructions for hardware replacement workflows under return instructions.
  • On the design and deployment side, our engineers can assist with MX sizing, MS access design, and the Aruba gateway exit plan via free CCIE support, including migration sequencing and rollback planning for your 13 branches.
  • Please note: Specific warranty terms and support services may vary by product and region. For accurate details, please refer to the official information. For further inquiries, please contact: router-switch.com.
