Season Migration Guide
What migration is, how your tier placement is determined, what carries over, and how to arrive on the new server in the strongest possible position.
What is Season Migration?
At the end of each season, players have the opportunity to migrate their account to a new server. Your migration score — based on HQ level, research, hero investment, and troop power — determines which tier bracket you are placed into on the new server. Migrating is optional: players who stay remain on their current server for the next season.
Migration Score Factors
Your migration score is a combined measure of account power. All of these factors contribute.
| Factor | Weight | Notes |
|---|---|---|
| HQ Level | High | One of the largest contributors. HQ30 is the target floor for competitive migration tiers. Each level above 28 adds significant score. |
| Research Completion | High | Badge-heavy trees (Military Strategies, Peace Shield, Alliance Recognition, T10 path) all contribute. More completed nodes = higher score. |
| Hero Stars & Skills | High | Total hero investment across your roster. Focus stars and skill books on your core 5 before migration to maximise this metric. |
| Troop Power (CP) | High | Total troop count × troop tier. T8–T10 troops weigh significantly more per unit than T4–T5. Higher-tier troops in larger quantities = better tier placement. |
| Building Levels | Medium | All buildings contribute to your base CP score. Camp, Lab, Alliance Center, and Military Center levels all count. |
| Gear & Equipment | Medium | Hero gear quality and enhancement level contributes to your power score. Orange-tier gear with high enhancement adds meaningful score. |
| VIP Level | Low | VIP level contributes a small amount to migration score. F2P players should not grind VIP specifically for migration. |
Migration Tiers
Elite
Requirement: High CP + HQ28+ + strong researchTop-tier migration bracket. Placed on servers with other high-power players. Maximum prestige but also highest competition on arrival.
Advanced
Requirement: Mid-high CP, HQ24–28Competitive placement. Good balance of strong alliances and room to grow. Most active mid-game players land here.
Standard
Requirement: Low-mid CP, HQ under 24Lower competition but also fewer alliance benefits. Growing players may find Elite servers more rewarding despite higher competition.
Carries Over ✓
- All buildings and their current levels
- All research progress (every node completed stays completed)
- All heroes and their star/skill levels
- All troops (type and tier preserved)
- All gear and equipment
- All items in your bag (speed-ups, resources, chests)
- VIP level and experience
- Alliance Recognition research
Resets ✗
- Server rank and leaderboard position (you start unranked on the new server)
- Alliance membership (you leave your current alliance; must rejoin or create on new server)
- Map position (your base relocates to the new server map)
- Server-specific titles (e.g. President title from Battle for the Capital)
- State-specific buffs and territory bonuses
Pre-Migration Strategy
Do these in the weeks before migration opens.
Maximise research completion before the window opens
Every completed research node increases your migration score. The weeks before migration are the highest-ROI time to burn badges — each node completed now boosts your tier placement on the new server.
Push HQ level if you are near a major threshold
HQ28, HQ30, and HQ32 are tier-inflection points. If you are within 2–3 weeks of a major level, it is worth prioritising that upgrade before migration to lock in a higher score bracket.
Star up your core heroes
Hero investment contributes to migration score. If you have fragments stockpiled, spend them before migration rather than carrying them over — starred heroes count; unspent fragments do not.
Do not spend resource items without queuing an upgrade
Resources in bags carry over; loose resources (food/wood in city) carry over too. But if you have a major upgrade queued before migration, it completes using resources you already spent — do not cancel upgrades mid-migration.
Co-ordinate with your alliance
Migrating together with your current alliance is far stronger than migrating solo and rebuilding. Agree on a target server in advance and migrate as a group on the same day.
Scout the destination server before committing
Check the leaderboard of target servers. Look for active alliances, a healthy mid-tier population, and a dominant alliance that is not excessively aggressive toward new arrivals. A server where the top alliance is friendly to growing players is worth more than raw match score.
Common Mistakes
- Migrating solo while your alliance stays behind — you lose all construction help, Zombie Siege coordination, and Alliance Duel benefits immediately.
- Migrating under-powered to an Elite server and being farmed on arrival by established players with months of head-start.
- Not maxing research before migration — every node counts toward score and you cannot go back.
- Carrying excess food/wood without a queued upgrade — resources can be raided on the new server the moment you land without a shield.
- Expecting the new server to be easier — if you migrate to a competitive server, the existing players have more time on that server and often stronger alliances.
- Forgetting to set a shield immediately on arrival — your base spawns without one and your location is visible to the entire new server.
