When using:

project -> Import...
JDBC Database >> Source Model,

Despite including the URL property VirtualDatabaseVersion=2 during the import process the version of the imported vdb I see when I create a deployable vdb archive is given as "1":

...
<import-vdb name="fileData" version="1" import-data-policies="false"/>

As an alternative I have tried setting the "version" property given here:

https://access.redhat.com/documentation/en-US/Red_Hat_JBoss_Data_Virtualization/6.2/html/Development_Guide_Volume_1_Client_Development/Connection_Properties_for_the_Driver_and_Data_Source_Classes1.html

But saw the same results the version of my imported VDB always seems to be "1"
