I used One-click migration beta to move my websites and database but I noticed that the database is empty in the new server aapanel 
Hello, is it normal to try to import data manually?
Yes it is normal when I tried to import the data manually. But it did not work when i used the One-click migration beta
Are there migration logs? My test here is normal.
/www/server/panel/logs/psync.log
The psync.log is not present in the directory
aaPanel_Kern The psync.log is not present in the directory
Need to check on old server
aaPanel_Kern It says it already exists but there are no records in the new database. Is there a way to clear the database in the new server and re-run the backup from the old server 
You can try to delete the relevant database in the new server. Run again
I have done it. It doesn't copy the database content.
Are there any relevant error logs? If it cannot be migrated, it is recommended that you migrate it manually.
