From Zero to Legacy Lab — Complete Bundle (PHP + JBoss)

Two technologies. Two environments. One method. Everything you need to stop guessing and start controlling.

The Legacy Lab Complete Bundle brings together both volumes so you can build and validate a full legacy lab — PHP and Java EE — without improvisation and without guesswork.

What you get:

Vol. 1 — PHP Legacy Lab

• Docker stack with PHP 5.6, PHP 7.4, and MySQL 5.7

• Two real case studies: HMS (CodeIgniter) and ChurchCRM (plain PHP)

• EOL-rescue mode for PHP 5.6 (Debian archive strategy)

• DEV/UAT/QA simulation in the same VM

Vol. 2 — JBoss Legacy Lab

• JBoss AS 7.1.1 + JDK 7 fully containerized

• MySQL JDBC driver as a permanent JBoss module

• Functional JNDI datasource tested via CLI

• Real test WAR (EmployeeServlet) deployed and validated

Across both volumes:

• Isolated VM with fixed IP (192.168.102.10)

• Operational scripts: start, stop, backup, bootstrap

• Healthchecks against the "false OK" trap

• Symptom-driven troubleshooting (20+ real scenarios)

• Final checklists — infra, stack, deploy

The method: Reproduce → Diagnose → Decide. Build the environment first. Collect evidence. Then make the decision: stabilize, upgrade, or migrate. No guessing. No flying blind.
