Here is the easiest way for you to migrate /re-deploy your existing served licences from standalone Windows virtual server to vApp managed appliance.  (One caveat here is to make sure that the current licenses have a non-zero overdraft count. Licenses created against a product code used by some distributors contain an overdraft count of zero.  The Flexera server on the vApp requires a Served license to have a non-zero overdraft count.)   Another clarification for the subsequent post:  I am not aware of any licensing versions( 5.4/5.9). If its PowerPath/VE versions then vApp does support all PowerPath/VE versions till date without requiring much license file changes if we follow the steps above.   Also, trial period of 45 days from vApp is available with PP/VE 5.9 and above. Hope this clarifies things.  In the remote case you need to maintain two ELMS servers( original Windows  sever and vApp), not recommended at all, I can provide steps for that too. But will hold on till there is a valid need expressed by you.  Thanks, Ankur PP/VE Dev  Manager.
I am wondering if anyone can help me w/some questions I have re: an upgrade or migration path. We are planning on installing the PPVE virtual appliance in our environment, which is an "upgrade" from our current environment which is running a served license model running on a virtualized windows server. I don't believe there is a direct upgrade path from our current enviroment, so I am planning on bringing up the virtual appliance and transitioning my hosts to the new license server, etc... I have some questions about this process that I can't seem to find documentation on; Any help is appreciated, Thank you
