Welcome to the Atlassian Community.

The JSON importer wizard is primarily a one-off tool designed for use through the UI. Although you can run it multiple times, I suggest automating your JSON data import process using the Jira REST APIs. The APIs allow for the bulk import of issues and offer a better format for handling your data. You can create a script to extract data from your third-party system, transform it to ensure compatibility with Jira, and use Jira REST APIs to bulk import your data.

Greate thanks for yours advice.

Cause the REST APIs can`t surpport a full JSON data way into Jira system.I may try to insert records data via SQL file into jiraissue table,and then use Jira REST APIs to bulk import other customfiled values and history change data into the new Jira instance.

Good luck to me. = =

Please don't. Don't insert data directly into the database. I'm sorry to highlight this in bold. It will likely cause other problems. APIs should do the trick for you. Please continue to explore APIs or alternative scripting solutions using apps. Feel free to share your challenges and limitations so we can assist, but don't insert data directly into the database.
