The "Feb-26-2024_p.m._1210_-_test_migrate_Zephyr_Scale_for_QA-__.7z" is a migration executed around 12:10 pm UTC+8 on February 26th, 2024.
The selected project in that migration is only the "QA-NTC-TRR" and it uploads almost all Zephyr Scale data.
But not 100% Zephyr Scale data are correct because our user found out that there are null values for some fields, please refer to the "Jira on Server" and "Jira on Cloud" screenshots.

Hope thesss attachments can help you investigate why the progress of Zephyr Scale keeps 17% for 3 days in the "Test migrate all data with attachment I" as captured in the "2024_03_05-02_05_04_921/Screen_Shot_2024-03-04_at_9.22.01_PM.png" screenshot.
