Ezoic Hosting Configaration

Can I remove all the things in Cpanel after moving my site into Ezoic hosting?
I have configured the E-mail service with 3rd party service. So what else needs to configure to remove things from the old Cpanel?
Ezoic already automatically added an ALIAS record as lb1.wphosting.ezoic.com to my DNS. Is that enough?

Highly appreciated it if you can give me some guide

Once you have moved over completely, you do not need to use your old hosting at all.
This depends on the third-party service, if it is completely hosting your email services, then there is nothing else that needs to be done.
Ezoic configures its own DNS records to take over hosting. The alias record acts as your main A record. Nothing else needs to be done in the DNS.
