I am migrating my website abc.com from one webhosting company to another in a shared hosting environment. Both have cpanel. And the second hosting account i am preparing to move is my multi-domain hosting account with 3 domains already in it.

The problem is, i have many email accounts associated with my website abc.com, which are accessed using webmail. So if i move it to the other host, will i lose all those accounts and their emails?

If yes, then how should i synchronise the email accounts so that all the accounts and the contained emails remain intact?

I saw some several sync tools like IMAP Sync, etc. But these require two hosts while synchronizing, and as you see, i have just one domain name to be synchronized over 2 servers.

PS, i do not have any ssh access on either of them, and i have made complete backup of all files using backup wizard in cpanel.
