My server is running on Windows Server 2003 and Windows Plesk version is 8.6.0.1. I and I need to transfer all my account/domains to Windows Plesk 11.0.9, how can this be done ?
try to upgrade your current version to plesk 10 and then try to migrate/upgrade it to 11. If you try to upgrade plesk to 11 directly then it can crash your current plesk.
