Moving two subdomains into single parent domain

[Sunil]

Dear All,

this query is for all members and plesk support team.

i have a situation like ex:there is main domain test.com ,i am using a forward server which forwards email to two server hosting two sub domains of test.com , x.test.com and y.test.com.

now i am migrating both server into one and i was to get rid of forwarding server combining both domains x.test.com and y.test.com ,where all email boxes will be moved into single domain test.com

Let me know is this is possible ,if yes just give me procedure how to carry on this.

Regards
Sunil
