What Is Transported vs Recreated in Production

4 min read
On this page

In this lesson, you will learn:

  • What moves between instances
  • What must be recreated
  • Why the difference exists

🔁 Quick look back: Last time: Building the Production Migration Matrix. You learned how the migration matrix lists how each item reaches production.

1 The Problem: Some Items Can’t Travel

Riya tried to put everything in one update set. But some items:

  • Belong to one instance, like MID Servers.
  • Are secrets, like credentials.
  • Differ by instance, like ranges.

🎯 The problem: Some Discovery items can’t or shouldn’t travel between instances.

👉 The fix: Know what moves and what’s rebuilt, and rehearse on snwrstage.

Compare transported and recreated items.
Figure 1. What moves and what’s rebuilt.

2 Why

  • A MID Server serves one instance.
  • Credentials are secrets; production values differ.
  • Dev and test scan small ranges; production scans everything.

💡 Good to know: Need a refresher? See Fundamentals › Update Sets for how update sets work.

3 Rehearsing

Move the update sets to snwrstage and set up its instance-specific items. This shows gaps before production.

4 Project Clear View: How We Implemented It

📍 Situation: Riya wanted to understand what moves.

🧭 Decision: Split the matrix into moved and rebuilt, then rehearse on snwrstage.

🛠️ Steps we took:

  1. Marked each row as moved or rebuilt.
  2. Moved the update sets to snwrstage.
  3. Checked every moved item arrived.
  4. Found one property left out, and added it.

✅ What we verified:

  • The rehearsal found one gap, now fixed.
  • The final update sets are ready for snwr.

📁 Evidence: Rehearsal notes and the final update sets.

5 Quick recap

  • Patterns, classifiers and rules move in update sets.
  • MID Servers, credentials and most schedules are rebuilt.
  • Rehearse on staging to find gaps.
  • Keep the matrix up to date.

6 Check yourself

Think of your answer first. Then tap to check.

1 Why are credentials rebuilt, not moved? Show answer

They’re secrets, and production values differ.

2 What did the rehearsal find? Show answer

One property that was left out of the update set.

3 Where was the rehearsal? Show answer

snwrstage.

Nice work! You know what moves and what’s rebuilt. 🎉
