Step 1: Score Your Current Stack
Before proposing migration, quantify the problem. Use WebPulse's Score Your Stack tool to generate a portfolio health assessment. A score of 35/100 is a conversation starter. Attach dollar amounts: hosting costs, maintenance hours, security audit findings, incident response costs from the past 2 years.
Step 2: Build the Business Case, Not the Technical Case
CTOs approve migrations. CFOs fund them. Your proposal needs both languages. Technical: 'We're running on a framework with 18,005 CVEs.' Financial: 'We're spending $38,000/year/site on maintenance for infrastructure that costs competitors $600/year.'
Step 3: Start with One Property
Don't propose migrating everything at once. Pick the simplest, lowest-risk property — usually a marketing site or blog. Migrate it. Measure the before and after: load time, hosting cost, maintenance hours, security scan results. Use those real numbers to justify the next migration.
Step 4: Parallel Run, Not Big Bang
The safest migration pattern: build the new site alongside the old one. Redirect traffic gradually. Monitor everything. If something breaks, traffic reverts. This eliminates the 'what if it fails' objection that kills most migration proposals.
Step 5: Measure and Expand
After the first successful migration, the numbers speak for themselves. Hosting cost dropped 90%. Load time dropped 70%. Security incidents dropped to zero. Maintenance hours freed up 3 developers. These aren't projections anymore — they're results. Use them to justify migrating the next property. And the next.
The Timeline
The organizations that start now will be fully modernized by 2028. The ones that wait will start the same journey later, at higher cost, with less talent available, and more technical debt to unwind.
