(sbs-manual, sbs-installer) throws Server Instance server does not have a system connector named null (6545145)

Description

When upgrading from Enterprise Server 8.0PE to 2.1, an error is thrown saying the server does not have system connector named null, and invalid user information as seen in sbs-manual. Even after changing the hardcoded values, the same error message is seen.

Solution

You can only encounter this bug while upgrading from a 8.0 PE toEnterprise Server. The workaround is to upgrade to either 8.1, 8.2, or 9.0 and then upgrade to Enterprise Server.
