You might want to ask what to do if you're going to migrate your web hosting previously to Hadoi.
Well, it's very simple, here's the step below:
1. Backup all the data (you could use cPanel backup if you intended or manual).
2. Order new web hosting package at Hadoi, of course, you have to settle any payment issue.
3. Then restore to the new web hosting at Hadoi (either cPanel backup or manual).
4. Change nameserver of your domain to ns1.hadoi.id and ns2.hadoi.id (ignore this if you also ordering a new domain).

That's it, best of luck !
