VMware Migration Readiness (Google Sheets Tool) vs Faddom

Stage-0 baseline (vCenter + backup CSVs, local) and Faddom agentless application mapping: how they fit together.

TL;DR

  • Purpose: Stage-0 = fast, local readiness baseline; Faddom = agentless application dependency mapping to visualize who-talks-to-whom and group move sets.

  • Inputs: Stage-0 uses vCenter + backup CSVs; Faddom observes live flows and system context via agentless discovery (deployment specifics vary).

  • Outputs: Stage-0 delivers per-VM readiness with reasons + exec rollups; Faddom delivers application/service maps, dependency graphs, and groupings to support wave planning.

What each does

Stage-0 Readiness Baseline (this tool)

  • Inputs: vCenter inventory CSV + backup job inventory CSV.

  • Runs locally: Google Sheets (and Excel), no agents, no SaaS ingest.

  • Normalization: deduped VM names, OS family, any-tag production/critical/compliance, uptime class.

  • Backup posture: missing/stale, short retention, irregular frequency, no offsite.

  • Output: Per-VM readiness with reasons (only causes that apply) and exec-ready rollups by Cluster / OS family / Uptime / Backup posture.

  • Why first: quickly separates move-sooner vs stabilize/leave-for-now cohorts before heavier discovery/mapping.

Device42 (brand)

  • Goal: produce agentless application dependency maps across on-prem and cloud to reveal relationships between services/VMs and help form move sets.

  • How: observe and analyze network/process communication (agentless deployment model) and build visual dependency graphs.

  • Output: Application/service maps, dependency graphs, and insights to support grouping, change control, and wave sequencing.

When to use each

  • Use Stage-0 when you need a triage baseline in hours with no connectors or agents, so you can brief stakeholders and decide where deeper effort is warranted.

  • Use Faddom to discover and validate dependencies, visualize application groupings, and support move-set formation and wave planning.

How they work together (handoff 1-2-3)

  1. Stage-0 shortlist: Identify cohorts (by cluster/OS/role) using readiness + reasons, backup posture, and uptime class.

  2. Targeted mapping in Faddom: Focus Faddom on shortlisted cohorts to confirm who-talks-to-whom, uncover hidden ties, and group move sets.

  3. Planning: Combine Faddom dependency maps with Stage-0 flags to shape stabilization tasks, pre-migration fixes, and wave sequencing.

What carries forward from Stage-0 (not throwaway)

  1. Deduped VM inventory with normalized names & OS family.

  2. Any-tag normalization for production / critical (DB/AD/DNS) / compliance.

  3. Backup posture flags (missing/stale/retention/offsite) informing RPO/RTO readiness.

  4. Uptime class to highlight change-averse systems.

  5. Cohort shortlist to constrain Faddom scope to high-value areas.

  6. Assumptions register and readiness rules table for governance/audit.

  7. Optional CSV bundle (inventory + flags + cohorts) to align teams without re-keying.

Can we continue guiding beyond Stage-0?

Yes. If deeper assessment is useful, we’ll help scope the right next step, ensure Stage-0 artifacts are reused alongside Faddom outputs, and keep assumptions consistent across discovery, mapping, and planning. Vendor-neutral.

What this page is not

A product review or endorsement. This page explains how a Stage-0 readiness baseline complements an agentless application mapping platform like Faddom.

Micro-FAQ

  • No. Stage-0 provides a readiness baseline from CSVs. Faddom provides agentless application dependency maps that support grouping and wave planning.

  • Deduped inventory, tag normalization, backup flags, uptime class, and cohort selection—plus thresholds/rules—focus mapping on the right systems.

  • Lower friction and faster signal; you limit scope to high-value cohorts and take cleaner inputs into mapping, reducing time and noise.
