I would be really glad if someone explains me how to transfer my website from plesk to cpanel, I have no idea what to do.
and what's gonna happen to my webmail?
can I create a new email in my new host and keep my last email on the old host? cause I can't get backup of it, or is there any easy way to transfer my current mail too?
Did you know, that cPanel offers "complimentary migration service for migrations from Linux versions of Odin Plesk (formerly Parallels) / DirectAdmin / Ensim, to cPanel."?
You are able to inform yourself at for example:
