Migration - Wordpress Multisite

I signed up for a trial and created a wordpress multisite. I used the migrate plugin to transfer the entire site. It worked without any issues.

My trial expired and my server was deleted.I added my credit card and created a new server. I reinstalled the plugin on my site and tried the migration again. When I launch the window, it shows that the files were already imported, and overall migration progress is going through.
Once the migration finishes, nothing actually got migrated.

How I do another clean migration?
