GoDaddy to Hostinger Website Migration

I'm looking to migrate my websites from GoDaddy to Hostinger. I don't currently have a backup of my website files and databases and they need to be taken.
Parallely, I also need help with creation of some email aliases using addy.io or some other such service.

The project will involve:

- Creating a full backup of my website files and databases on GoDaddy.
- Transferring these files and databases to a Hostinger plan.
- Ensuring the website is fully operational post-migration.
- Setting up different email aliases as per my requirements


Ideal candidate :

- Has rich experience in website migration, especially with GoDaddy and Hostinger platforms.
- Proven expertise in backing up website data.
- Understands email setups
- Substantial knowledge in fault checking and post-migration troubleshooting.

Please bid with detailed proposed steps and backup strategies. Looking forward to a seamless website migration!
