Legacy modernization intelligence · weekly, monthly and quarterly

Who is replacing legacy systems, before the vendor is chosen.

By the time a modernization project reaches a request for proposals, the shortlist is usually set. Sunset Signals reads public filings, hiring data and government records every week to find organizations that are about to replace legacy systems, and tells you who they are, what they are retiring, and how far along they are, while there is still time to be on that list.

What is in an issue

Not market trends. Named organizations, and the reason this quarter matters.

A named organization and system

Who it is, which system or technology is being retired, and how far along they are: planned, selecting, or already under way with phases still ahead.

Why now

The forcing function: end of vendor support, an audit finding, a merger integration date, a new technology executive, or the role they just posted.

One click to the source

Every claim links to the filing or posting it came from, so you can verify it before you pick up the phone.

What a signal looks like

Three signals from a recent weekly brief, as subscribers saw them.

United Airlines Chicago, IL Job posting, Sep 17 ↗

Hiring the manager who will take a legacy system off the mainframe

What they posted

Senior Manager, Application Development. The role builds a multi-year product roadmap that begins with migrating the legacy system off the mainframe to a cloud-based application.

Why now

They are hiring the person who will own the roadmap, which is about as early as a signal gets. No partner is mentioned.

State of South Carolina West Columbia, SC Job posting, Sep 11 ↗

ColdFusion, Classic ASP and legacy .NET moving to Azure

What they posted

Lead Platform Engineer, two openings. The role owns the application modernization roadmap: plan and execute migrations from ColdFusion, Classic ASP and legacy .NET onto modern frameworks and Azure.

Why now

Two leads hired at once to run a named migration roadmap.

PetMed Express (PETS) Delray Beach, FL SEC 10-K, Jun 2 ↗

Planning an ERP and finance-system replacement

What they said

Planning a transition to a modernized ERP and financial system to cut reliance on the legacy systems behind its IT general control deficiencies. The material weakness was not fully remediated as of March 31.

Why now

An open audit finding puts a clock on it, and no vendor or integrator is named yet.

Three editions

The quarterly is free. The weekly brief and the monthly digest name every organization, with the details a sales team needs. One reader per subscription, and the weekly includes the monthly.

Quarterly report

Free

Ten signals that defined the quarter, named in the emailed edition, and the pattern across everything else: what is being retired, how early, why now, where.

Weekly brief

$49 a month · founding pilot: 3 months for $49

Every organization that showed a signal that week, while the decision is still open: what they posted or filed, why now, the stack on each side of the move, who owns it, and where to find them.

Start the founding pilot

Monthly digest

$19 a month · founding pilot: 3 months for $29

Every organization named in the month, grouped by what you sell, with the month's pattern in charts. For teams that plan in months rather than weeks.

Start the founding pilot

Teams and firms: seats for everyone who works the accounts, a shared archive and custom watchlists. Inquire for pricing.

Who reads it

Business-development and practice leads at firms that sell modernization work. Each issue is organized by what you sell, so you read your section and skip the rest.

What you can rely on

Machines do the reading. A person makes the call.

Breadth you could not staff

Thousands of public documents a week, across corporate, hiring and government sources. Public and licensed sources only: nothing from behind a login, and no contact lists.

One standard, applied every time

Every candidate is held to the same written standard, built from 25 years of running these projects: is it real, is it theirs, is it early enough to matter.

A person decides

Nothing reaches an issue on a model's say-so. Every item is read and approved by someone who has done this work, and every claim links to its source so you can check it.

Who curates it

Robert Encarnacao has spent 25 years modernizing legacy systems, from Visual Basic, PowerBuilder, Delphi and Informix 4GL to modern .NET and cloud, most recently as a Principal AI Solutions Architect. Robert writes about AI systems and modernization at bitandbeing.com.
