Remote invoke from wM7.1 to wM6.1

hello every one .

right now we are using wM7.1 and from that we want to invoke a service in 6.1. In the admin panel for 7.1 i created alias and tested it .The test was succesful but from developer when i am trying to invoke the remote service its throwing an error .

Can we invoke a remote service in 6.1 from wM7.1 environment???

thanks in advance


As mentioned above i tried to remote invoke wM6.1 service from wM7.1 but was unable to do so .So i used webmservices to execute a service on 6.1

Did any of you guys tried remotely invoking the service on wM6.1 from wM7.1
