V 4.5.19 to 5.1.61 - Cpanel Migration issue

I have downloaded both JSON and CSV from previous installation and moved all my files to new hosting using backup. It basically failed to work. I have installed fresh version and seems the new version is 5.1.61 however seems interface is also changed and now rather than one json / csv file it categorises everyhing into different branches?

How can i use backup file from V4.5.19 to new version 5.1.61?
Can someone please help

(self host / with app)



If you’re moving between servers we recommend using mysqldump
