Similar to another thread, but I'm using a newer configuration:

ZCM 11.3.0 with embedded Sybase database
NSD 7.1 appliance, external MySQL database

I have followed all the various appropriate sections of documentation - some of which match the reality of the software, some not so much - and get a consistent error in the log file:

It seems as though there are valid schemas for each of the databases as each of the products are, independently, working just fine and accessing their respective databases without issue.

Customer really needs to have the HW/SW import work so that there are items to manage through the product.

Best regards -
