What would we be migrating from... asking what our current setup would be called. What's the difference and what does the migration entail? Is there a reason why our VAR would have setup us not as LDS? Just trying to figure it out. Thanks. 

It really depends on the VAR.  It also depends on when your system was implemented as it wasnt always available.  Are you on RIO or Avante?  If you are on RIO already then it would involving getting SSL certs or all your appropriate server and configuring the system.  If you are on Avante it would involve you installing the LFDS and adding all of your users and groups there.  Then do the above steps as well.  I would very much ask your VAR to do this as there are quite a few steps/setup.
