Migration Problem from Plesk 7.5.6 (windows) to (.2.3

[AsifI]

Hi,

I am trying to migrate my sites from an old server (plesk 7.5.6 for windows) to plesk 9.2 without a success.

I get the following error: Host xxx is not accessible. I have seen similar questions asked in other threads with some suggestions but none of them worked for me.

Any suggestions
