Some embodiments provide a method for configuring a DCN migrated from a first host computer at a first site of multiple sites spanned by a logical network to a second host computer at a second site. At the second host, the method receives, from the first host, data for configuring the DCN and implementing the logical network on the second site. The data includes (i) data particular to the first site and (ii) a global identifier for a logical port to which the DCN attaches. The method provides the global identifier to a local logical network manager, which uses the global identifier to retrieve data regarding the logical port from a global network manager that manages the logical network across the sites. Based on data retrieved from the global network manager, the method modifies the data particular to the first site into data particular to the second site.
