Say I have a domain (.com.my) registered through a local web hosting company (W1). The registrant, administrative and billing contact are mine. The technical contact is W1. The nameservers listed belong to W1. There is no website, only a "parked" page listing W1 contact info.

Say I now want to have my website, but it is being done by another web hosting company (W2). I know for .com, .net etc domains, there is the transfer of registrars. how about for .com.my domains?

Do I need to transfer the domain from W1 to W2?

How do I change the info so that my domain refers to the new web site done by W2? Do I have to do that? Or ask W1 to do that? Or will W2 contact W1 and do that?
