Migrating Existing Cpanel domain to Virtualmin

Hi, Nice to be here.

I try to migrate my existing wordpress site from Cpanel to Virtualmin. I follow some guide to proceed the migration. It ends up failed. The error info is like this “Validating migration file …The specified domain is already hosted by Virtualmin”. What does this mean?

Thanks for any soonest reply!

Old question, just posting an answer in case it helps someone.
It just means you have already setup a virtual server with a domain name that exists in the cpanel migrating package.
Solution is either change domain name of the existing virtualmin virtual server, or remove the domain from the cpanel package to migrate.
