We are operating about five years a large NetXMS system.
The current version of our NetXMS server is v2.0.8 I have tried
to upgrade this  to v2.1, but the upgrade process was not successfuly.
Please find in the attachement the screenshot about it.
We use the MSSQL 2012 SP3 database engine.
Do you have any idea how is possible to correct this issue?

Thank you in advance.
