ACCOUNT ANALYSIS BRIEFING // MIGRATION SCORE PROTOCOL
How to Calculate Your Migration Score in Last Z: Survival Shooter (And Why You Can't Cheat It)
Every migration cycle, the same question floods alliance chats: "how do I lower my Migration Score before the calculation hits?" It's a fair question — a lower score means a cheaper Identity Tier and fewer passes spent. But most of the advice circulating around this topic is wrong, and acting on it can cost you real planning time. This guide covers what actually determines your score, why the popular "strip your gear" trick doesn't hold up, and how to use the numbers honestly to plan your move.
What Actually Determines Your Migration Score
Migration Score is a comprehensive rating of your account's overall development, not a snapshot of your troop count on a given day. It draws from several profile categories, weighted unevenly:
Structure / Building Power
One of the two heaviest contributors to your final score.
Tech Power
The other primary contributor — research investment carries real weight here.
Hero Power
Contributes to the score, but at a lower rate than Structure and Tech Power.
Mod / Vehicle Power
Also a secondary factor — meaningful, but not decisive on its own.
Troop Count
Has no measurable impact on your score at all, according to documented player analysis across multiple servers.
The "Strip Your Gear" Myth — Why It Doesn't Work
You'll see this tip repeated in a lot of places: unequip hero gear and remove tank components right before the migration calculation to artificially lower your score. Based on the most consistent player-documented reports, this does not actually work.
This matters because acting on the myth costs you something real: time spent stripping gear that could've gone toward actually useful pre-migration prep, plus the risk of leaving your account weaker than it needs to be heading into a new, unfamiliar state.
What You Can Actually Do
- Know your tier before the event is even announced. Since the score reflects long-term development rather than a manipulable snapshot, the only real lever you have is knowing where you stand well in advance — not scrambling to change it at the last second.
- Use a calculator to preview your Identity Tier and pass cost. Plugging in your current Structure, Tech, Hero, and Mod Power gives you a realistic estimate of your tier before migration opens, so you know exactly how many passes to start saving for.
- Start saving passes the moment you know your likely tier. If you're free-to-play and expecting Medium tier or higher, the weekly Glory Shop pass limit means you need to start buying months in advance — there's no way to catch up once the event window opens.
- Plan your account development with your target tier in mind. Since Structure and Tech Power carry the most weight, big investment decisions in those categories are what actually move your tier over time — not last-minute gear swaps.
Preview Your Migration Tier Before the Event Opens
Plug in your current Structure, Tech, Hero, and Mod Power to see your estimated Identity Tier and pass requirement — so you can start saving with real numbers instead of guessing.
Open the Migration CalculatorIdentity Tier Reference
Regular — ~10 passes
The most flexible tier. Can migrate freely into open Regular slots during Phase 3 without needing an invitation.
Medium — ~15 passes
Requires an invitation or Special Immigration Application, even during the Free Migration Phase.
Advanced — ~20 passes
Slot competition intensifies here, especially for Flourishing States.
Elite — ~50 passes
The steepest cost and tightest slot availability. Often requires direct presidential approval, and Flourishing States may have zero open Elite slots.
Common Migration Prep Mistakes
- Not buying enough passes early. The Glory Shop's one-per-week limit punishes late planners severely.
- Trying to manipulate power at the last second. As covered above, destroying troops or lowering visible strength does nothing to your score.
- Skipping pre-event communication. A state's public listing doesn't guarantee you a slot — relationships with leadership do.
- Having no backup plan. Slot counts change in real time; always have a second-choice state ready.
- Forgetting the technical requirements. Alliance membership, active combat, and outgoing troops all block migration outright — clear all three before attempting the move.

Frequently Asked Questions
Can I lower my Migration Score by unequipping gear before the event?
Based on the most consistent player-documented evidence, no. Migration Score reflects your account's overall development history, including peak power, not a real-time snapshot — so temporarily removing gear right before calculation does not change your tier.
Does troop count affect my Migration Score?
No. Documented analysis across multiple servers shows troop count has no measurable effect on the score. Structure Power and Tech Power are the primary contributors, with Hero Power and Mod Power as secondary factors.
How can I find out my Identity Tier before migration opens?
Use a Migration Score calculator with your current Structure, Tech, Hero, and Mod Power to get a realistic preview of your tier and pass cost ahead of time.
Why is the jump from Advanced to Elite so expensive?
It's a deliberate design choice. Elite accounts face the highest pass cost, the fewest available slots, and typically require direct presidential approval — this discourages runaway power concentration in top-performing states.
Final Thoughts
The honest path to a favorable Migration Score isn't a last-minute trick — it's knowing your tier early, using a calculator to plan realistically, and saving passes well before the event window opens. Skip the gear-stripping myth and put that time into actual preparation instead.
