Engineering Operations

Migration Playbook: Switching Without Friction

Swapping a daily driver mid-project is costly. Follow this three-step checklist to evaluate Claude Code and Windsurf on equal terms before standardizing your team.

01

Export Config, Prompts & Data

Inventory what each candidate needs: prompt libraries, templates, connected accounts and project files. Export from your current stack first so Claude Code and Windsurf start from the same baseline.

SETUP: SAME BASELINE

02

Map Pricing to Your Real Usage

Compare published entry tiers against your expected volume. Claude Code starts at $17/mo (subscription); Windsurf starts at Freemium (freemium) — model the monthly cost at your actual workload before committing.

ECONOMICS: PUBLISHED TIERS

03

Run a Two-Week Parallel Trial

Run both tools on the same live tasks for ten working days. Score outputs against the five Airecmark dimensions, then let the 2.2-point composite gap — not vendor marketing — decide the standardization call.
