Yes.

You can import existing SimpleViewer 1.9 galleries into svManager.

You can also create new SV 1.9 galleries but this feature is hidden by default. You need to make a small change in a configuration file to see SV 1.9 in the list of new gallery options. More information in http://www.simpleviewer.net/svmanager/support/#sv19

However.

SimpleViewer 2 has many advantages. Now might be a good time to re-create your existing galleries in SV 2.
