The Export License step is part of the license transfer procedure in the Configure AppDNA Environment wizard. In this step AppDNA exports the license transfer token to the file you specified in the previous step. This locks the database. After this process has finished, click Close to exit the wizard.
You are now ready to move the AppDNA license server to the new machine. Typically you do this by installing the AppDNA server on the new machine.
You then need to import the transfer token into the database in order to unlock the database and reactivate the license against the new AppDNA license server location. For step-by-step instructions, see "Import the license transfer token" in Transfer Licenses.
