Switching Watch Brands? How to Migrate Sports Data Between Garmin, COROS & Huawei
Why Your Data "Disappears" When You Switch Watches
Every sports watch brand has its own cloud platform — Garmin Connect, COROS App, Huawei Health. These platforms don't talk to each other.
You ran with a Garmin for 3 years, accumulating thousands of activities and VO2max history. One day you switch to COROS, open the app — nothing. The data isn't gone; it just never left Garmin's servers.
This is the #1 headache for anyone switching sports watch brands. Here are the three most common scenarios:
Scenario 1: Garmin → COROS
The most common upgrade path. COROS has grown rapidly with excellent value in the PACE and APEX lines. But COROS's EvoLab training platform needs historical data to establish accurate fitness baselines — without migration, you're starting from zero.
Scenario 2: COROS → Garmin
Moving into the Garmin ecosystem means your Training Status, VO2max estimates, and training load all depend on long-term history. Without migration, the first few weeks of training recommendations will be significantly off.
Scenario 3: Huawei / Xiaomi / Apple Watch → Pro Sports Watch
Many runners start with entry-level devices and upgrade to Garmin or COROS. These beginner platforms (Huawei Health, Mi Fitness, Apple Health) rarely offer data export, making manual migration nearly impossible — but not with GarSync.
3 Steps to Migrate with GarSync
Step 1: Connect Both Platforms
In GarSync's Account Management, add both your old and new watch platforms. Example: add Garmin (old) + COROS (new). OAuth one-tap authorization takes under a minute.
Step 2: Create a Migration Task
On the Sync page, create a task: Source = old platform, Target = new platform. Enable "Sync History" and select all sport types you want to migrate.
Step 3: Let It Run
GarSync pulls your full history from the old platform and uploads each activity to the new one. Smart deduplication prevents duplicates. Hundreds of activities typically migrate in 10-20 minutes.
What You Get After Migration
- Complete activity records: distance, pace, heart rate, power — preserved as-is
- GPS tracks: including map routes and elevation profiles
- Raw FIT files: auto-backed up to your NAS after binding a SAMBA account and creating a sync task
- Training continuity: new platform's load, VO2max trends, and fitness status calculated from full history
FAQ
Q: Will the new platform recognize these "foreign" activities?
A: Yes, in most cases. GarSync uploads standard FIT files with complete fields (device type, sensor data, GPS coordinates). The new platform recalculates derived metrics like training effect and VO2max using its own algorithms.
Q: Does migration cost extra?
A: Same pricing as regular sync — free trial + pay-as-you-go with bulk migrations capped. If you have hundreds of historical activities to migrate, the cap makes it extremely affordable. Subscribe at $4.99/month for unlimited free sync.
Q: Can I use Strava as a middleman instead?
A: Two big problems with Strava as a bridge: (1) Strava doesn't store raw FIT files, so you lose sensor-level details; (2) Strava's API restrictions make exporting to third-party platforms complex. GarSync connects platforms directly via official APIs and preserves every data field.
Q: Will I lose data during migration?
A: No. GarSync reads from the old platform and writes to the new one. If an upload fails (e.g., target server hiccup), the task retries. Your original data stays safe on the old platform throughout.
