Migrate Yeastar Cloud PBX to P-Series Cloud Edition

Step 1. Obtain backup files
Contact Yeastar Support to obtain backup files for your Cloud PBXs.
Step 2. Delete provisioned phones
To avoid auto-provisioning conflicts, delete provisioned phones from the original PBX. After migration, the server address will change, and phones must be re-provisioned on the new PBX.
Step 3. Delete the original PBX
Delete the original PBX instances from the YMP platform.
Note: This step will initiate system downtime. During this period, all telephony services will be unavailable until the new PBX is fully restored and operational.
Step 4. Prepare target PBX
On Yeastar Central Management, create P-Series Cloud PBX instances with the required firmware version.
For more information, see the following topics:
Step 5. Restore backup
Restore the backup to the target P-Series Cloud PBX instance either through Yeastar Central Management or directly on the specific P-Series Cloud PBX instance. For more information, see Restore a Cloud PBX backup on P-Series Cloud Edition.
Step 6. Verify and configure system after restoration
After restoring from the backup, perform the following tasks on the new PBX:
  1. Confirm that all supported settings and data have been successfully migrated.
  2. Verify SIP trunk registration status.
    Note: For peer trunks, update the server information with your ITSP to ensure correct trunk peering and connectivity.
  3. Reset your IP phones to initiate auto-provisioning with the new PBX.
    Note: If provisioning fails, follow the corresponding configuration instructions for the P-Series PBX system to complete the setup.
  4. Test internal and external calls.
