Since you're wanting to move from a shared hosting environment to a VPS, and you're working with a slightly large backup, you may be better off seeing if Bluehost will provide you with a TAR archive of your data + databases.

The reason I recommend asking them to perform the backup for you is because without SSH access on their servers, backups that large on a shared hosting performed from a web browser are going to fail and fail often. This is more so due to the limitations imposed by shared providers.

If they can provide you with a TAR archive, you could simply use wget to pull the backups over to your Droplet, extract them and then move your web files to the directory of your choice and then we can restore the database using the MySQL command line utility once a database and user has been created on the Droplet.

It's going to be far easier to restore your database from the CLI than it will be to dump it using either phpMyAdmin or Adminer, and far quicker.

Thank you @jitter for the for you quick response, I really appreciate your effort for the community. Before i go and check on bluehost can you suggest me some video, guide or documentation which can help me to migrate.

For server software you can just install ready Nginx image from DO. There are also some tutorials like "perfect server" https://www.howtoforge.com/tutorial/perfect-server-ubuntu-with-nginx-and-ispconfig-3/ . In stead of using back up for moving your site, you may use transfer.website . First transfer is free.
