Blue Archive cross progression works through account linking or the in-game account-transfer system: bind your existing account before changing devices, then sign in or enter the transfer details on the new Android or iOS device. Your students, currencies, campaign progress, Cafe development, and raid records move with the account, but you should not expect separate regional servers, guest accounts, or different operating-system profiles to merge automatically.
What Blue Archive Cross Progression Actually Supports
Blue Archive is primarily a mobile RPG, so its progression is stored on the game account and server rather than only on the phone. That means an established account can generally be continued on another compatible device after it has been linked correctly. Android-to-iOS and iOS-to-Android transfers are the main use case; moving from one Android phone to another is also straightforward when the same login method or transfer credentials are used.
Account-bound progress includes your Sensei Level, unlocked students, student levels, equipment, skills, Unique Weapons, lessons, lessonschedule progress, Cafe development, Momotalk relationship progress, commissions, story chapters, event progress, and Total Assault records. A roster containing characters such as Yuuka, Shiroko, Hoshino, Ako, Himari, or Mika is therefore not rebuilt from zero on the new device.
The same applies to normal account resources, including Pyroxenes, Credits, Activity Reports, Activity Reports for specific experience tiers, Enhancement Stones, Superior Artifacts, Secret Tech Notes, and crafting materials. However, the exact treatment of paid currency, promotional items, and platform-specific purchases can depend on the regional version and store rules. Check the official Blue Archive website before spending heavily immediately before a platform switch.
Cross progression is not the same as cross-server play. Global, Japan, Korea, Taiwan, and China versions are separate services with different publishing arrangements, banners, maintenance schedules, and account databases. A Global account cannot normally be imported into the Japanese client simply because both applications are called Blue Archive. Installing the correct regional version is the first requirement.
How to Link or Transfer Your Blue Archive Account
On the old device
First, open Blue Archive and confirm that the title screen loads the correct Sensei account. Check your player name, level, roster, and current server before touching the transfer menu. This prevents the most common mistake: transferring a newly created guest account while assuming it contains the original data.
From the lobby, open the menu and enter the account, settings, or account-management section. The wording can change after client updates and can differ by language, but look for Account Link, Account Transfer, or a comparable account-protection option. Use an available supported login method, such as the platform account or email-based option shown by your regional client. If the game offers a transfer code and password, generate both and record them exactly; do not rely on a screenshot that may be inaccessible after the phone is lost.
Before leaving the old device, verify that the account-management screen shows the account as linked. Also record your UID or player identification details, server region, and the last successful login. These details help Nexon Player Support identify the account if a transfer fails.
On the new device
Install the same regional client from the official store, complete the initial download, and reach the title screen. Choose the account-link or transfer option rather than tapping through as a new guest. Sign in with the same linked credentials, or enter the transfer code and password supplied by the old device. Allow the game to restart if prompted, then check the lobby for the original Sensei Level and students.
Do not delete the old installation until this check is complete. A correct result should show more than the same nickname: inspect the student roster, Pyroxene balance, Cafe furniture, campaign stage, and the current event screen. If any of these belong to a fresh account, stop and return to the title screen instead of progressing further on the wrong profile.
What Moves, What Does Not, and Why It Matters
The safest way to think about Blue Archive progression is that it follows the account database, while the app itself only provides access to that database. Your student investment therefore moves with the account. If you raised Tsubaki to level 87, upgraded her EX Skill, equipped Tier 8 gear, and improved her bond through Momotalk, those changes belong to the profile rather than the original handset.
Temporary states deserve more caution. AP regeneration continues according to the account clock, but the visible amount can change while the client is offline. Event shop purchases, claimable mailbox rewards, daily tasks, Total Assault attempts, Tactical Competition placement, and recruitment pity counters should be checked before switching. Take screenshots of important banners and currencies, particularly when a limited recruitment campaign is close to ending.
Paid Pyroxenes are the biggest platform-related warning. On some games, paid currency can be restricted by the store or operating system on which it was purchased. Do not assume that paid and free Pyroxenes will behave identically after an Android-to-iOS move. The account may still be intact even when a purchase balance is displayed differently. Contact support with receipts rather than attempting a second purchase.
Blue Archive also does not combine two profiles. If you have one guest account with Haruna and another linked account with Makoto, transferring one does not merge their students, Pyroxenes, Cafe items, or recruitment history. Choose the account you want to preserve before linking anything. This is more important than optimizing early progression; our team synergy guide covers a different game, but the same principle applies: protect the correct profile before rebuilding a roster.
Common Cross-Progression Problems and Fixes
A new account appears
This usually means the new client was started as a guest or authenticated with a different Google, Apple, Facebook, or email identity. Close the game, return to the title screen, and select the transfer or linked-account option. On Android, check which Google account is active on the phone; on iOS, verify the Apple account used for the original link. Clearing app data can remove local guest access, so only do this after confirming that the original account is protected.
The transfer code fails
Re-enter the code and password manually, checking capitalization, zeroes, the letter O, and accidental spaces. Confirm that the code belongs to the correct regional client and has not been replaced by a newer code. Never post transfer credentials in Discord, social media, or a support screenshot. Anyone with usable credentials may be able to access the account.
Progress looks behind
Finish the login process and restart the application on a stable connection. Server maintenance, delayed synchronization, or an old client build can make the lobby appear incomplete. Compare the Sensei Level, student roster, Cafe level, and most recent recruitment rather than relying on the home-screen layout alone. The official notices page is the best place to check maintenance and service interruptions.
If the account remains inaccessible, use the official Nexon support request page. Include the UID, server, account nickname, approximate creation date, device history, purchase receipts, and screenshots of the original profile. Do not send your password publicly. For broader mobile performance issues, compare the practical settings advice in Steamoz’s mobile graphics performance guide, but remember that graphics settings cannot restore a missing account.
Best Practices Before Switching Devices
Perform the move when you have time to verify every system. Finish or note any active recruitment, claim mailbox rewards you do not want to risk missing, and record your Pyroxene totals. Confirm the exact region, link the account, and test the credentials on the new device while the old device still works. Keep the old phone logged in until the new lobby displays the correct Sensei Level, roster, Cafe, and campaign stage.
Finally, enable the strongest account-protection method offered by your version of Blue Archive and keep recovery information private. Cross progression is reliable when the account is properly bound, but it cannot rescue an unlinked guest profile after a factory reset, lost phone, or accidental overwrite. Once the transfer is verified, update the client and avoid creating a second guest account on the new device. That simple checklist is the difference between continuing a developed roster and starting over at the tutorial.
For players managing several live-service games, the same account-security discipline is useful alongside Steamoz’s device and platform guide. In Blue Archive specifically, the rule is straightforward: link first, transfer second, and verify the profile before deleting anything.
