A Python tool that parses Cisco UCM bulk-export TAR files offline and produces interactive Plotly visualizations to guide your Webex Calling migration: user dependency clusters, phone readiness, and dial-plan analysis.

Why use this playbook

• Know before you migrate: Identify tightly coupled users — shared lines, shared phones, hunt groups, BLF subscriptions — so you can sequence migration waves without breaking calling workflows.
• Device gap in minutes: Get a supported-vs-unsupported Cisco phone breakdown from your actual export data before ordering or planning replacements.
• Dial plan clarity: Visualize translation patterns, CSS combinations, and route patterns as interactive charts instead of raw CSV rows.
• No live system access needed: Runs entirely offline against a standard UCM BAT export; no AXL credentials or network access to UCM are required.
• Scriptable foundation: The ucmexport.Proxy class exposes typed containers for every UCM object type, making it easy to write custom migration queries.

What it does

• Parses UCM BAT export TAR archives into typed Python objects via the ucmexport library (phones, end users, hunt pilots, DNs, CSS, locations, etc.).
• Builds a user dependency graph using NetworkX — connects users via shared phones, shared lines, hunt pilots, BLF subscriptions, and call pickup groups.
• Renders Plotly interactive sunburst, Sankey, and 3D graph charts in the local browser for migration readiness review.
• Provides a CLI utility to strip sensitive columns from export CSVs (transform_tar.py) before sharing archives across teams.
